  • Audiometry

    An audiometry exam tests your ability to hear sounds. Sounds vary, based on their loudness (intensity) and the speed of sound wave vibrations (tone).

    Hearing occurs when sound waves stimulate the nerves of the inner ear. The sound then travels along nerve pathways to the brain.

    Sound waves can travel to the inner ear through the ear canal, eardrum, and bones of the middle ear (air conduction). They can also pass through the bones around and behind the ear (bone conduction).

  • Beta 2 Glycoprotein IgG

    Beta-2 glycoprotein 1 antibody is an autoantibody that is associated with inappropriate blood clotting. This test detects and measures beta-2 glycoprotein 1 antibodies in the blood.

    Beta-2 glycoprotein antibody is considered one of the primary autoantibodies called antiphospholipid antibodies that mistakenly target the body?s own lipid-proteins (phospholipids) found in the outermost layer of cells (cell membranes) and platelets. This test is often ordered along with tests for other antiphospholipid antibodies, including cardiolipin antibody and lupus anticoagulant.

    Antiphospholipid antibodies interfere with the body?s blood clotting process in a way that is not fully understood yet. They increase the risk of developing inappropriate blood clots (thrombi) in both arteries and veins.

    Antiphospholipid antibodies most frequently develop in people with the autoimmune disorder called antiphospholipid syndrome (APS). This condition is associated with widespread blood clots (thrombotic episodes), a low platelet count (thrombocytopenia), or with pregnancy complications such as pre-eclampsia and recurrent miscarriages, especially in the second and third trimesters.

    Also, some people with autoimmune disorders such as lupus (systemic lupus erythematosus, SLE) may begin to produce one or more of these autoantibodies, which can put them at risk of forming blood clots in blood vessels.

  • Beta HCG total

    HCG appears in the blood and urine of pregnant women as early as 10 days after conception. Quantitative HCG measurement helps determine the exact age of the fetus. It can also assist in the diagnosis of abnormal pregnancies, such as ectopic pregnancies, molar pregnancies, and possible miscarriages. It is also used as part of a screening test for Down syndrome.

    This test is also done to diagnose abnormal conditions not related to pregnancy that can raise HCG level.

  • Bicarbonate

    What is this test?
    This test measures the amount of bicarbonate, a form of carbon dioxide, in your blood.

    Bicarbonate, also known as HCO3, is a byproduct of your body’s metabolism. Your blood brings bicarbonate to your lungs, and then it is exhaled as carbon dioxide. Your kidneys also help regulate bicarbonate. Bicarbonate is excreted and reabsorbed by your kidneys. This regulates your body’s pH, or acid balance. Bicarbonate also works with sodium, potassium, and chloride. These substances are called electrolytes. These are often measured at the same time as bicarbonate.

  • Bilirubin (T+D)

    A bilirubin test measures the levels of bilirubin in your blood. Bilirubin (bil-ih-ROO-bin) is a yellowish pigment that is made during the normal breakdown of red blood cells. Bilirubin passes through the liver and is eventually excreted out of the body.

    Higher than normal levels of bilirubin may indicate different types of liver or bile duct problems. Occasionally, higher bilirubin levels may be caused by an increased rate of destruction of red blood cells (hemolysis). Bilirubin testing is usually done as part of a group of tests to check the health of your liver. Bilirubin testing may be done to:

    Investigate jaundice ? a yellowing of the skin and eyes caused by elevated levels of bilirubin. A common use of this test is to measure bilirubin levels in newborns to check for infant jaundice.
    Determine whether there might be blockage in your bile ducts, in either the liver or the gallbladder.
    Help detect liver disease, particularly hepatitis, or monitor its progression.
    Help evaluate anemia caused by the destruction of red blood cells.
    Help follow how a treatment is working.
    Help evaluate a suspected drug toxicity.

  • Bleeding Time (BT)

    Bleeding time is a medical test that measures how fast small blood vessels in the skin stop bleeding. A blood pressure cuff is inflated around your upper arm. While the cuff is on your arm, the health care provider makes two small cuts on the lower arm. They are just deep enough to cause a tiny amount of bleeding.

    The blood pressure cuff is immediately deflated. Blotting paper is touched to the cuts every 30 seconds until the bleeding stops. The provider records the time it takes for the cuts to stop bleeding

  • Blood group

    Blood typing is a method to tell what type of blood you have. Blood typing is done so you can safely donate your blood or receive a blood transfusion. It is also done to see if you have a substance called Rh factor on the surface of your red blood cells.

    Your blood type is based on whether or not certain proteins are on your red blood cells. These proteins are called antigens. Your blood type (or blood group) depends on what types your parents passed down to you.

    Blood is often grouped according to the ABO blood typing system. The 4 major blood types are:

    Type A
    Type B
    Type AB
    Type O

  • Blood sugar fasting

    A fasting blood sugar test measures sugar (glucose) in your blood. It?s a simple, safe and common way to diagnose prediabetes, diabetes or gestational diabetes. A healthcare provider will prick your finger or use a needle to draw blood from a vein in your arm. Don?t eat or drink anything (except water) for 8 to 12 hours before the test.

  • Blood sugar post prandial

    Postprandial means after a meal. This test is done to see how your body responds to sugar and starch after you eat a meal. As you digest the food in your stomach, blood glucose, or blood sugar, levels rise sharply. In response, your pancreas releases insulin to help move these sugars from the blood into the cells of muscles and other tissues to be used for fuel. Within two hours of eating, your insulin and blood glucose levels should return to normal. If your blood glucose levels remain high, you may have diabetes.

  • Blood sugar random

    If you have diabetes, paying close attention to your symptoms is very important. Be sure to test immediately if you feel you?re experiencing symptoms of low blood sugar. Random blood glucose readings can help you identify hyperglycemia and decrease the risk for some chronic complications.

    Testing your blood glucose levels at various times throughout the day can help you manage your diabetes and reduce your risk of diabetes complications. The only way you can know what your blood sugar level is to test it on a regular basis. andom glucose testing isn?t a substitute for your normal glucose testing schedule. You should also perform fasting tests and tests after meals, as suggested by your doctor.

    A fasting blood glucose test is usually performed upon waking, before you eat. Testing after meals measures glucose levels around two hours after the start of a meal. Different testing times will yield different results. These are affected by:

    the food you?ve eaten
    stress
    medications you?re taking
    any exercise you?ve done
    For some people, it?s important to test every day. This helps you get a sense of your overall blood sugar control and can help you make treatment decisions. Testing is the best way to learn how your blood sugar is affected by your lifestyle, medications, or both.

  • Blood urea nitrogen (BUN)

    A common blood test, the blood urea nitrogen (BUN) test reveals important information about how well your kidneys are working. A BUN test measures the amount of urea nitrogen that’s in your blood.

    Here’s how your body typically forms and gets rid of urea nitrogen:

    Your liver produces ammonia ? which contains nitrogen ? after it breaks down proteins used by your body’s cells.
    The nitrogen combines with other elements, such as carbon, hydrogen and oxygen, to form urea, which is a chemical waste product.
    The urea travels from your liver to your kidneys through your bloodstream.
    Healthy kidneys filter urea and remove other waste products from your blood.
    The filtered waste products leave your body through urine.
    A BUN test can reveal whether your urea nitrogen levels are higher than normal, suggesting that your kidneys may not be working properly.

  • C-Peptide (Fasting)

    A C-peptide test is often used to help tell the difference between type 1 and type 2 diabetes. With type 1 diabetes, your pancreas makes little to no insulin, and little or no C-peptide. With type 2 diabetes, the body makes insulin, but doesn’t use it well. This can cause C-peptide levels to be higher than normal.

    The test may also be used to:

    Find the cause of low blood sugar, also known as hypoglycemia.
    Check if diabetes treatments are working.
    Check on the status of a pancreatic tumor.
    Why do I need a C-peptide test?
    You may need a C-peptide test if your health care provider thinks you have diabetes, but is unsure whether it is type 1 or type 2. You may also need a C-peptide test if you have symptoms of low blood sugar (hypoglycemia). Symptoms include:

    Sweating
    Rapid or irregular heartbeat
    Abnormal hunger
    Blurred vision
    Confusion
    Fainting
    What happens during a C-peptide test?
    A C-peptide test is usually given as a blood test. During a blood test, a health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.

    C-peptide can also be measured in urine. Your health care provider may ask you to collect all urine passed in a 24-hour period. This is called a 24-hour urine sample test. For this test, your health care provider or a laboratory professional will give a container in which to collect your urine and instructions on how to collect and store your samples. A 24-hour urine sample test generally includes the following steps:

    Empty your bladder in the morning and flush that urine away. Record the time.
    For the next 24 hours, save all your urine passed in the container provided.
    Store your urine container in the refrigerator or a cooler with ice.
    Return the sample container to your health provider’s office or the laboratory as instructed.
    Will I need to do anything to prepare for the test?
    You may need to fast (not eat or drink) for 8?12 hours before a C-peptide blood test. If your health care provider has ordered a C-peptide urine test, be sure to ask if there are any specific instructions you need to follow.

  • C-Peptide (PP)

    What is a C-peptide test?
    This test measures the level of C-peptide in your blood or urine. C-peptide is a substance made in the pancreas, along with insulin. Insulin is a hormone that controls the body’s glucose (blood sugar) levels. Glucose is your body’s main source of energy. If your body doesn’t make the right amount of insulin, it may be a sign of diabetes.

    C-peptide and insulin are released from the pancreas at the same time and in about equal amounts. So a C-peptide test can show how much insulin your body is making. This test can be a good way to measure insulin levels because C-peptide tends to stay in the body longer than insulin.

  • C-Reactive Protein (CRP)

    A c-reactive protein test measures the level of c-reactive protein (CRP) in your blood. CRP is a protein made by your liver. It’s sent into your bloodstream in response to inflammation. Inflammation is your body’s way of protecting your tissues if you’ve been injured or have an infection. It can cause pain, redness, and swelling in the injured or affected area. Some autoimmune disorders and chronic diseases can also cause inflammation.
