How can I get lab services at One Medical?

You can talk to your health care provider about any lab tests you're interested in having, either during your visit or by email. Typically, our providers will order tests as needed based on your visit, any health conditions you're managing, or medications you're taking. Providers may ask for tests at regular intervals to help monitor certain health conditions, but it's common that healthy younger people - for example, those in their 20s and 30s - won't need frequent lab tests.

When are the on-site labs open?

Please refer to the local office pages for specific lab hours.

Will insurance cover my lab tests?

Every insurance plan is different, and the details of your coverage depend on your specific policy. While most lab tests are generally covered by insurance, you may want to contact your carrier before visiting the lab in order to ensure coverage.

If I’m new to One Medical, should I have labs done prior to my first visit?

No. In order to make sure we don’t waste your time or money, we’d like to meet you first. Your provider then can assess which tests are needed and write you the appropriate lab orders. You can transfer your existing medical records to us electronically - just use the medical record request form in My One.

Should I fast before my lab test?

In order to get accurate results with some lab tests, it may be necessary for you to fast in advance. Your provider will discuss how to prepare for any lab tests you need. If your lab test requires fasting, you won’t be able to eat or drink anything besides water for 12 hours before your test, though it’s alright to take needed medication. Plus, being well hydrated makes it easier to draw blood during your test.

How and when will I get my lab test results back?

Once you complete your lab test, it will be processed by one of One Medical’s third-party partners. The lab report will be reviewed by a health care provider on our Virtual Medical Team and then emailed to you, typically within seven to 10 business days. The board-certified provider who reviews your test will explain the results and advise you on the next steps.

Can I get STD and HIV testing done at One Medical?

Yes. We keep STD test results completely confidential, as we do with all medical tests. If you believe you were exposed to HIV or viral Hepatitis, contact your provider immediately to discuss early preventive treatment options.
