Health services designed to meet your changing needs.

Lab Services

Convenient Laboratory Services

One Medical Group offers our members on-site laboratory services on a walk-in basis, with no need for an appointment. Our staff will put you at ease, draw your blood and collect other specimens in an anxiety-free environment, and get you on your way quickly. After we receive and review your results, we will promptly email you with our interpretation and a copy of the report.

Your health care provider will order the specific tests you need based on your age, your medications, your overall health status and the amount of time since your last set of blood tests. Young, healthy individuals may only need blood tests every five years, while patients with active medical issues may need tests annually or even more frequently. If you are interested in having specific tests performed, you can discuss them with your provider in the office or via email before coming in to have your blood drawn.

Fasting Tests

Some tests are accurate only if you have been fasting before having your blood drawn. If your provider tells you that you need to fast before your tests, then you should not eat food or drink anything besides water for a minimum of 12 hours prior to the test. You may take medications during this time, and you should drink plenty of water in order to stay hydrated and help make your blood draw easier.

STD Testing

Like all medical tests, STD tests are strictly confidential. If you'd prefer to have your STD tests performed elsewhere, you can go to the City Clinic at 356 7th St. in San Francisco (call 415-487-5500 for more information and hours). If you know you were exposed to HIV or viral hepatitis, you should speak with your physician immediately to discuss early preventive treatment options.

Insurance Coverage

Insurance plans vary, and your coverage depends on your specific policy. While most tests are covered by insurance, you may want to contact your insurance carrier to ensure coverage before having your test done.

Off-Site Testing

If you prefer, you can go to an off-site lab such as LabCorp, Quest Diagnostics, CPMC, UCSF or any local medical center for your tests. Please contact them directly for their respective locations/hours.
