This site is subject to updates and you should "refresh" each time you access this site

CPT Codes

The CPT Codes provided are based on AMA Guidelines and are for informational purposes only. CPT Coding is the sole responsibility of the billing party. Please direct any questions regarding CPT Coding to the payer being billed.

Panels and Profiles

If you have any questions regarding the individual components of a panel or profile, please cross-reference your hard copy version of Quest Diagnostics Reference Manual or Directory of Services or call your Quest Diagnostics Representative. Tests offered in any Quest Diagnostics panel or profile may be ordered individually using the Quest Diagnostics Test Requisition Form.

Reflex Tests

Quest Diagnostics offers its clients three types of reflex testing; standard required reflex tests, standard reflex tests and client specific reflex tests. Clients order reflex testing when they want additional tests performed automatically if the results of the first test meet or exceed the specified criteria. This range is determined by either medical experts at Quest Diagnostics in accordance with standard medical practice or by the client. The reflex test is almost always an additional charge above the initial test.
