A comprehensive list of questions that you would be likely to ask when your doctor asks you to come for a checkup. If you want more information about a certain test please feel free to Contact Us if you have more questions

1. What does it mean by fasting?

Fasting is when you consume no food or drinks, with the exception of water, for a set period of time. It's important to drink plenty of water, not just because you're not eating, but because it's easier to draw blood from your veins when you're well hydrated.

2. For which test fasting is required?

Fasting is essentially required for Lipid Profile and Fasting Glucose test. Also Fasting may be required in cases of special (hormones) tests or on Doctor's advice.

3. How much time after lunch should we give blood sample?

Blood sample should be given exactly 2 hours post lunch for Post lunch Glucose test. The lunch should include only routine food which the patient has regularly. Patient should not eat or drink anything during these 2 hours except water.

4. How to collect a urine sample?

Urine sample should always be collected in the sterile clean container. Before collecting the sample, the patient has to clean the surrounding area (genitals). While passing the urine patient should discard the first part of the urine and collect the ensuing part. This sample is also called as Mid-stream urine sample. The container should be labelled properly and the cap tightly screwed to avoid leakage of the sample.

5. How to collect 24 hours urine sample?

  • Empty your bladder when you first get up in the morning. DISCARD this Urine. Record the time on the container.
  • From that time, save all urine up to and including the first morning specimen at the end of the 24 hours ( or other designated time period). During collection and until the specimen is brought to the laboratory, the urine container should be refrigerated or kept on ice (in a bucket).
  • Record on the urine container, the time the last part of the specimen was collected.
  • Be careful not to deposit toilet tissue in the specimen or allow it to become contaminated with fecal material.
  • If the container has a preservative, (orange sticker or written), handle the container with caution.
  • Bring the container with the urine to the laboratory as soon as possible.

9. Why should you know your blood group?

For all practical and routine purposes, it is ideal to transfuse to the patient the same group of blood which he/she belongs to. It is only under very dire emergencies that we take O group as universal donor and AB groups as universal recipient. Under no circumstances O group can get any other blood except O. Similarly A group patient cannot be given B group blood and vice versa.
