Where Can I Get Blood Work Done
There are different locations that offer laboratory services that include blood work. Most hospitals contain a laboratory that you can visit to get tests done. Some laboratories will have walk-in options. Others may require an appointment.
Additional locations for blood testing may include:
- Private laboratories. Hospitals may use private labs to offload some testing from their own laboratories, or in cases when a specialized test is needed. Often, health insurance plans will require you to use a specific laboratory that is in their network for the test to be covered.
- Point-of care. This describes situations when you may need to get a blood test wherever you are receiving medical care. In routine scenarios, this typically
Results may take anywhere from a few hours to a few days to become available. Heres an overview of how long some common tests may take:
- complete blood count : 24 hours
- basic metabolic panel: 24 hours
- complete metabolic panel: 24 to 72 hours
- lipid panel: 24 hours
Timing can depend on the specific lab where you get tested, and how many tests you get done at once. If you order multiple tests, you may not get the complete results until all of the tests are completed.
Sometimes a lab will only release results to your doctor, who reviews them and then releases them to you.
How Is Blood Glucose Monitored
If youre diagnosed with diabetes, youll be asked to monitor your blood glucose levels daily to determine the amount of glucose in your blood. Your diabetes health care team will work with you to determine the best times during the day to test your blood glucose and to find the monitoring device that best suits your needs. There are many accurate blood glucose meters available, and theyre simple to operate. You prick your finger with a lancet and apply a drop of blood to a treated strip. A glucose meter then reads the strip and displays the value.
Monitoring blood glucose and making appropriate changes offers a more independent, self-sufficient approach to diabetes management. Research indicates that complications associated with diabetes may be reduced if blood glucose levels are kept near normal. Blood glucose monitoring can help you:
- Make changes in your daily diet, medications or activity
- Identify low blood glucose levels
- Control blood glucose during illness
Continuous glucose monitoring technology uses a wearable or implantable sensor to monitor blood sugar levels and communicate data via a phone app or receiver-style device. Personal CGM devices are considered the standard of care for patients with Type 1 diabetes and are increasingly common for those with Type 2 diabetes. CGM technology allows patients to view their results in real time and for those results to be shared with their doctor.

The A1C test is not used to diagnose gestational diabetes or type 1 diabetes.
Also, if you have a condition that affects your red blood cells, such as anemia or another type of blood disorder, an A1C test may not be accurate for diagnosing diabetes. Kidney failure and liver disease can also affect A1C results. In these cases, your provider may recommend different tests to diagnose diabetes and prediabetes.

What Are Blood Glucose Tests Used To Diagnose
Glucose testing is primarily done to diagnose or manage type 1 diabetes, type 2 diabetes, and gestational diabetes. Diabetes is a condition that causes your blood glucose levels to rise.
The amount of sugar in your blood is usually controlled by a hormone called insulin. But if you have diabetes, your body either doesnt make enough insulin or the insulin produced doesnt work properly. This causes sugar to build up in your blood.
If left untreated, chronically elevated levels of blood sugar can lead to other serious conditions including kidney disease, blindness, and heart disease.
In some cases, blood glucose testing may also be used to test for hypoglycemia. This condition occurs when the levels of glucose in your blood are too low, usually lower than 70 milligrams per deciliter .
Hypoglycemia can occur in people with diabetes if they take too much of their medication, like insulin, exercise more than usual, or skip a meal. Less commonly, hypoglycemia can be caused by other underlying conditions or medications.
Doctors consider very low blood sugar to be a medical emergency, as it can lead to seizures, coma, and even death.
Risks Of High Glucose
There are two types of diabetes: type 1 and type 2. In type 1 diabetes, the immune system attacks and destroys the pancreatic cells that make insulin. In type 2 diabetes, your body cannot make enough needed insulin or use it properly. This is the most common form of diabetes.
Diabetes can cause hyperglycemia. Blood glucose levels higher than 130 mg/dL while fasting or higher than 180 mg/dL two hours after eating indicate hyperglycemia. Additionally, a level of blood glucose higher than 200 mg/dL anytime is considered hyperglycemia.
Blood sugar levels that are too high can:
- Cause more frequent urination as the kidneys try to pass excess blood glucose through urine
- Increases a persons thirst, which increases the risk of dehydration
Severe low blood sugar can lead to more serious issues like feeling very weak, difficulty walking, and blurry vision. It can also lead to seizures, or involuntary movements and possibly a loss of consciousness.

Is Having High Blood Glucose Dangerous
In short, it can be. Zanini says that untreated high blood glucose can lead to a wide range of health issuesâsome of the most common being chronic inflammation, heart disease, vision impairment, kidney disease, nerve damage, tooth decay, damaged blood vessels, and periodontal disease.
Having high blood glucose also puts us at risk of mitochondrial dysfunction and oxidative stress. The former is a condition in which mitochondria fail to produce energy for cells. The latter occurs when free radicals outnumber antioxidants in the body and increase the risk of disease and other damage.
Phipps notes to avoid these risks, catching high blood glucose early on, then taking action to treat it is extremely important.
Is The A1c Test Used During Pregnancy
Health care professionals may use the A1C test early in pregnancy to see if a woman with risk factors had undiagnosed diabetes before becoming pregnant. Since the A1C test reflects your average blood glucose levels over the past 3 months, testing early in pregnancy may include values reflecting time before you were pregnant. The glucose challenge test or the oral glucose tolerance test are used to check for gestational diabetes, usually between 24 and 28 weeks of pregnancy. If you had gestational diabetes, you should be tested for diabetes no later than 12 weeks after your baby is born. If your blood glucose is still high, you may have type 2 diabetes. Even if your blood glucose is normal, you still have a greater chance of developing type 2 diabetes in the future and should get tested every 3 years.

How To Lower Blood Sugar
Its best to always talk to your doctor about what to do if a certain situation presents itself. For example, your doctor may recommend you take an additional dose of insulin to lower blood sugar. Make sure youre aware of the dose that should be taken, as well as what level it should be taken at.
While lowering blood sugar for some requires taking insulin or other medication, there are some simple things that can be done to help get blood sugar moving in the right direction.
Drinking water is a simple, effective way to help lower blood sugar. It wont get you all the way back to normal when your blood sugar level is very high, but it will usually help get it moving downward. When your body needs to get rid of extra glucose, it can dispose of it through urine. In order for this to happen, you need to be properly hydrated.
Additionally, exercising can serve as a long term proactive means of lowering average blood sugar. When you exercise, your body becomes more sensitive to insulin in your body and can pull sugar from the blood to use for energy. This is another effective way to lower your blood sugar levels naturally. Make sure that the exercise youre doing isnt too strenuous. Even going for a walk can be the exercise the body needs to use some of the excess glucose in the blood.
Understanding Your Diabetes Diagnosis
Diabetes can cause major health problems if you do not keep your blood sugar in check. However, you can stay healthy and feel good despite your diagnosis if you follow your doctor’s recommended treatment plan and maintain a healthy lifestyle. By choosing foods wisely, exercising regularly, maintaining a normal weight, reducing your stress level, and making other modest lifestyle changes, living with diabetes will be easier.

How Does Blood Sugar Level Work
With a lack of nutrients and food that contain glucose, the blood sugar level will begin to decline. This is known as hypoglycemia.
After blood sugar becomes low, the pancreas releases a peptide hormone called glucagon. When this happens, the glucose that is stored in the body for energy is instructed to release due to the liver. This causes the glucose to turn into glycogen, known as the glycogenesis process. This is what can help a body to regain energy as the readily stored glycogen, in the liver and muscles, will release into the body.
On the other hand, the blood sugar can also rise and become too high which is known as hyperglycemia.
When the body does not produce enough of the insulin hormone, blood sugar levels begin to increase. This is because glucose relies on the insulin hormone to help it absorb into the bloodstream. Usually, this occurs when the body cannot produce enough insulin, known as type 1 diabetes, or does not respond to insulin correctly, known as type 2 diabetes.
Eating too many processed foods can also cause your blood sugar level to rise. If there is not enough insulin present in the body, too much bad food can cause your blood sugar level to build up.
For those with a normal blood sugar level, this will be due to eating the right foods and your body being able to produce and respond to insulin.
You may be wondering what exactly causes an imbalance in blood sugar levels, so here is a roundup:
Type 1 Diabetes And High Bgls Can Be Serious
If you have type 1 diabetes, blood glucose levels above 15mmol/L can be very serious. Your body will try to get energy from fat stores and as a result produce ketones, which in large amounts are toxic. Dont wait for symptoms! Try and work out the cause/s, and bring your blood glucose levels back into range. Talk to your doctor or diabetes educator for advice and have a sick day plan ready.
If your blood glucose levels are higher than 15mmol/L for six hours or more, you have elevated ketones, and/or you feel unwell, start your sick day plan. This fact sheet explains, when to follow them, what to include, tips on staying well and when to seek urgent medical help.

How Does High Blood Sugar Affect The Body
Monitoring your blood sugar is essential if you have diabetes. Symptoms will get worse if treatment is not provided, and serious health complications can arise as a result. The signs of high blood sugar to look for include fatigue, blurred vision, and headaches along with:
- Frequent urination and thirst: Excess sugar in the blood is passed through the kidneys and into urine. This draws more water into the urine which means more frequent urination. High glucose levels cause thirst even when you are drinking enough fluids.
- Weight loss: Elevated blood sugar levels over time can lead to unexplained weight loss as a result of cells not getting the glucose they need. As a result, they start burning fat instead.
- Numbness: High blood sugar can cause tingling and numbness in the extremities. It is important to note that this is a complication of long-term diabetes and uncontrolled blood sugar levels.
What If It Goes Untreated
Hyperglycemia can be a serious problem if you don’t treat it, so it’s important to treat as soon as you detect it. If you fail to treat hyperglycemia, a condition called ketoacidosis could occur. Ketoacidosis develops when your body doesn’t have enough insulin. Without insulin, your body can’t use glucose for fuel, so your body breaks down fats to use for energy.
When your body breaks down fats, waste products called ketones are produced. Your body cannot tolerate large amounts of ketones and will try to get rid of them through the urine. Unfortunately, the body cannot release all the ketones and they build up in your blood, which can lead to ketoacidosis.
Ketoacidosis is life-threatening and needs immediate treatment. Symptoms include:
- Shortness of breath
Talk to your doctor about how to handle this condition.

How To Calculate Your Blood Sugar Level: The Complete Guide
To get an accurate reading of your blood sugar level, the best and most effective method is using a glucose meter. This will involve a small prick in your finger so receive a blood sample. The strip is then inserted into the meter and tested.
You may be wondering what your reading should be. There is no normal reading, an ideal reading differs from person to person. Everyone will get different readings at different times of the day. However, there is a rough range to determining a low, normal and high blood sugar level. Blood sugar level is read in mmol/L, which stands for millimoles per liter. Here is a guide as to what an ideal reading is for each diabetic type and non-diabetic patients:
|4 5.9 mmol/L< 7.8 mmol/L||4 5.9 mmol/L< 7.8 mmol/L|
It is advised to check it regularly if you are concerned, show regular symptoms or have diabetes. You should check before meals, exercise, before bedtime and after driving. Everyone is different so it is best to ask your doctor if you are unsure how many times and when you should check your blood sugar levels.
Research shows that over 50% who try to estimate their blood sugar level reading are incorrect. This may be due to over underlying medical conditions that did not know they had or poor lack of judgement. Therefore, this suggests it is very important to test at home to check in on your levels regularly to avoid any unnecessary future complications.

Causes Of High Blood Sugar
The leading causes of high blood sugar or hyperglycemia include:
Diet: Glucose comes from food, so what you are eating causes high blood sugar. Carbohydrates are the most common culprit as they are broken down into glucose very quickly in the body. High-sugar foods, high-fat foods, and processed foods also cause blood glucose spikes and should be replaced with healthier options.
Stress: When you are stressed, more stress hormones and chemicals are released, which drives blood sugar levels up too. If the stress is only temporary, this is not a serious issue, but if you experience chronic stress or an anxiety disorder, you may experience high blood sugar levels more often.
Metabolic Syndrome: These are a collection of conditions that occur at the same time and increase your risk for type 2 diabetes. High blood pressures, excess fat around the waist, and high cholesterol or triglycerides are examples of these conditions. When these occur in the body together, your risk for diabetes increases as does your blood sugar and the risk for potential complications.
Physical Inactivity: A lack of physical activity contributes to elevated blood sugar. When you are physically active each day, insulin works more efficiently, and your blood sugar can be maintained.
Symptoms Of Blood Blood Sugar Levels
Symptoms of blood sugar levels differ depending on if it is high or low. To determine which way the blood sugar have moved, the symptoms for each are typically:
|High Blood Sugar Symptoms|
|Slow healing wounds||Turning pale|
If symptoms are left untreated, more extreme circumstances can happen such as fainting, weakness, disorientation, vomiting and dehydration. When you notice symptoms, usually more than one at one time, it is advised to see a doctor right away.
It is important to get the right treatment so that you can return to a healthy normal blood sugar level and inhibit it from occurring again.
Treatment methods vary from the severity of the blood sugar level, whether it is high or low and if the patient has existing medical conditions, such as diabetes. Here are ways in which blood sugar levels can be treated:
