1. What is fasting?
    Fasting requires that you do not eat or drink anything except water for 12–14 hours prior to lab testing. Additional Instructions: 
         • Drink plenty of water when fasting
         • All medicines should be taken
         • Black coffee and plain tea are permitted (no milk, sugar or sugar substitutes)
  2. Do I need to fast?
    Fasting depends on the tests you are scheduled for. The following tests require fasting: Glucose, Chem-12 Comprehensive Metabolic Panel, Chem-7 Basic Metabolic Panel, and Lipid Panel
  3. Do I need to make an appointment?
    Appointments for routine lab work are not necessary. Patients are seen on a first-come, first-served basis.
  4. Does it matter which location I go to?
    Patients may go to any of our four outpatient labs or the main hospital lab. We encourage patients to go to the outpatient labs for ease of parking and registration. At the outpatient locations, you can register directly at the lab. At the main hospital, you need to go to Admitting to register before going to the lab.  
  5. Can I get a copy of my results?
    If your physician permits you to have a copy of your lab results, "Copy to Patient" will be on the order. Your results will be sent via U.S. Mail, or you can pick them up (ID required). Results will not be faxed or e-mailed. A copy of your results is also available through Medical Records.
  6. Will my insurance pay for this?
    Marin General Hospital Laboratories accept most insurance. Medicare does not cover certain tests. In order to have the testing performed, Medicare patients are asked to sign an advanced beneficiary notice (ABN), so the laboratory may bill you directly. If you have any questions, please contact Patient Financial Services at 1-415-475-4637.
  7. Where can I get information about what is included in a lab test?
    The Lab Tests Online website is an excellent resource designed to help patients, family members, and caregivers better understand the many clinical lab tests that are part of routine care. The information on Lab Tests Online is not intended to be a substitute for consultation with a physician or other appropriate health care provider or annual physical examination.
