Quest Diagnostics provides test results for most lab tests within 24 hours of receiving test samples. However, some lab tests take several days or even weeks to finish, as Quest Diagnostics explains.
Quest Diagnostics sends test results directly to the health care provider that ordered them. A patient may receive test results online if his doctor has made the required arrangements with Quest Diagnostics. Otherwise, the patient must receive test results from his doctor or request a copy from Quest Diagnostics; receiving this copy can take up to 30 days, according to Quest Diagnostics. Physicians can also request that the lab send test results to the patient; these results are typically received within 10 days.
