Preparing for your lab test

Do I need to fast?

Unless otherwise specified by your physician, there are four tests for which you are required to fast:

I take daily prescription medications. May I take my pills before I have my blood drawn?

Patients on coumadin (blood thinning medication) may take their daily dose. Patients on therapeutic drugs such as digoxin, phenytoin, etc., should wait until after their blood is drawn to take their next dose.

When will my doctor have the results?

Most tests are completed the day you come in for your testing with your physician receiving the results the following day. However, some tests are sent out to a reference laboratory. The turnaround time for these tests may vary. Please ask a lab staff member if you would like more information on when to expect the results to be forwarded to your physician. Please contact your physician's office for interpretation of the test results.

How do I collect my urine, sputum, or stool specimen?

To collect urine

More about urine collection >> 

  • The cup is sterile inside; do not touch inside lid.
  • Before collecting a urine specimen, you must clean yourself well to ensure collection of an uncontaminated specimen.
  • Urinate directly into the specimen cup. Replace the lid without touching the inside of the container.
  • The specimen can be placed in the refrigerator prior to transport to lab (but must be brought to the lab within 2 hours of collection or within one hour for a urine culture).
