Certain lab tests may come back in the "normal" range. Reference ranges do not always mean "optimal." Patients may still experience symptoms in the "normal" range. It is important to speak with a qualified health practitioner regarding normal vs optimal.
Currently, NY, NJ, and RI state laws prohibit direct-access testing. This lab test cannot be conducted at lab locations within these states at this time.
