C-Peptide (Fasting)
₹658.00
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.
