Before visiting ESCL you may want to ask your provider:

  • What laboratory tests are being performed?
  • Why does the testing need to be done and what does it test for?
  • What type of specimen is needed for testing?
  • When can I expect to hear about my lab test results?

*Disclose to your physician if you are currently taking biotin (Vitamin B7).

Sometimes special preparation is necessary to improve the accuracy of laboratory testing. This may involve:

  • Fasting (not eating any or certain foods) for several hours or overnight and possibly even avoiding coffee with cream/sugar until after laboratory testing has been performed.
  • Drinking more or less water than usual.
  • Avoiding certain medications or vitamin and herbal supplements prior to testing.  

It is important to consult with your provider about the medications you are currently taking, including supplements and other over-the-counter medications, before making any changes to your routine prior to having laboratory tests performed.

If you are bringing your specimen to the lab, there may be special instructions for the collection of or transportation of the specimen. If you are not certain if special preparation is required, contact your provider’s office or the laboratory for instructions.

If you did not follow the preparation instructions you received, let the staff at the patient service center know upon your arrival and prior to specimen collection.
