What do I need to do to prepare for the test?

Your doctor or nurse will give you the test instructions. You will need to collect your urine for 24 hours. Then, a blood sample will be drawn from you.

Your doctor may ask you to stop some medications temporarily if they are believed to affect the test accuracy. These medications include antibiotics and stomach acid pills. You should tell your doctor what other medications you have been taking. Also, DO NOT stop taking any medications before talking to your doctor.

Will I feel any pain during the test?

The urine test involves only normal urination. You should not feel any pain or discomfort during this part of the test.

The blood test involves inserting a needle to draw a blood sample. Patients’ feelings vary from mild pain to a prick or stinging feeling. It is also possible to feel some throbbing or have a slight bruise. All of this discomfort goes away quickly.

What happens if I forget to collect one urine sample during collection?

Collecting urine samples throughout the entire day is important for the accuracy of the test. For this reason, skipping one urine sample may affect the results. Please call your doctor’s office to find out whether you should continue collecting or stop and start all over again the next day.
