Laboratory Services

How long does it take to receive test results?
Depending on the test performed, most tests are completed and reported to your ordering healthcare provider within about 24 hours of receiving the sample for testing. Certain tests take several days to weeks. Results are sent directly to the ordering healthcare professional. Please ask your healthcare provider to contact you when your test results have been received.

How can I receive a copy of my test results?
Please contact your healthcare provider or Outpatient Medical Records Department to obtain copies of your test results. The Laboratory is prohibited from giving patient results to anyone other than licensed providers.

Can the laboratory help me interpret my results?
Please address questions related to interpretation of your test results to your personal healthcare provider. Your doctor will interpret your laboratory test results (that is, determine their meaning) in conjunction with information about your medical history, physical examination, and other test results, and provide you with medical advice, diagnosis or treatment.

Are my results confidential?
Yes. This laboratory adheres to test result information disclosure laws. The laboratory report is sent to the ordering physician or other authorized person who has requested the test. Please contact your clinician for further information regarding your results.

My doctor has ordered lab tests, but I cannot come during the Laboratory Working Hours. What can I do?
To arrange for testing outside of normal hours, contact the Client Services Customer Advocate or Laboratory Department customer advocate. Special arrangement can be made if needed.

My outside provider is requesting a copy of my results. Can you fax the provider a copy?
The Phlebotomy Desk can provide you with a form to request release of results to outside providers, and will fax the results once a signed release is received. The form asks for the provider's name, office phone number, and fax number, and requires the patient's signature with proper identification. You may submit the form at the same time as you have your blood drawn, but the patient (or parent/guardian for minors) having the testing performed must sign the release in person.

My provider has requested a test that requires fasting. What is required?
Eating or drinking can cause inaccurate results on some tests. We ask that for those tests that you refrain from eating or drinking anything other than water or prescribed medications for 12 hours before these tests are collected.

My provider has ordered a 3-hour glucose tolerance test. What do I need to do in advance?
Glucose tolerance tests require an appointment, usually scheduled in the morning. You will be given a special diet that you need to follow for three days before testing, and you need to be fasting for the last 12 hours. For your safety, you will need to remain in the area for the full three hours of the test. You may make an appointment by coming to the Phlebotomy Desk in Building 9, 2nd Floor, or you may phone (301) 295-2100.

What do I need to bring with me?
You will need to bring your military or dependent identification card. Your green addressograph card, obtained from Outpatient Medical Records, would be helpful if a urinalysis is required.
