Lab Visits

One of the most important factors in determining the accuracy and reliability of your lab test is you, the patient. Proper preparation is key to achieving the most accurate results.

Important Reminders

Important Reminders for All Lab Visits

  • Follow instructions, if there are any, to prepare for the specific test you are having performed.
  • Alert the person collecting your sample if you have deviated from the instructions and how.
  • Inform the doctor or practitioner of any medications (including vitamins and supplements) you might currently be taking or foods you have eaten within the day prior to the test.
  • If you are taking prescribed medications such as blood-thinners or seizure medication, write down the exact time at which you took your dose and when your blood was drawn. This information will be useful if your doctor has any questions about your test results.
  • Certain behaviors may affect some test results, such as recent or excessive exercise, not taking in enough fluids (dehydration), excessive eating, or recent sexual activity. You may be asked to refrain from some of these activities for certain tests.

Do lab tests require special preparation?

It should be noted that many tests require no special preparation. But for those that do, be certain to adhere to the instructions provided. If you are ever unclear about the instructions, be sure to ask the person ordering the test for clarification. If you are not given any instructions, you should ask if there are any special instructions needed to prepare for the test.
