Most are usually ready within around 72 hours. However, there are some tests – such as the HbA1c blood test – that can take up to a week to return results. The coeliac blood test and the test for vitamin D, meanwhile, are outliers, often taking as long as 2 to 3 weeks. Why does it all take so long?

This is generally 2-5 business days from the time the sample is received, depending on your test. If you are waiting for lab results in CA, KY, MD, or PA, your lab results may be held for a period of time before they are released. This hold time is in place to comply with state-specific laws.

Most test orders are valid for at least six months (unless your doctor has specified otherwise). If your lab testing order is more than six months old, please contact your doctor for a new form. Was this helpful? What should I expect when I have a lab test?
