Q:

Do I have to fast before my blood tests?

A:

Many common blood tests are performed on fasting specimens. Your doctor will let you know if your test requires you to fast. If you are unsure, please ask.

Q:

How long should I fast?

A:

If you are having fasting blood work, you should not consume anything except water, black coffee or tea for the 12 hours prior to your blood draw. The more you drink the better.

Q:

If I have to fast, can I still take my regular medications?

A:

Yes, take any medications you typically take in the morning unless you doctor tells with you otherwise.

Q:

Why is my doctor ordering this test?

A:

Lab tests are done to diagnose medical conditions, for health screening, and to monitor treatment.

Q:

Why do I have to have a certain test repeated?

A:

Your doctor may want to confirm the results for a prior test, or to monitor the status of a disease or treatment.

Q:

How long does it take to get my lab results?

A:

The most common tests are performed daily in our own laboratory. Less common tests are sent to a reference lab and may take longer. Your provider may send your results to you in a letter which includes the “reference range” for each test.
