Educational use only. Lab interpretation depends on context, medications, recent illness, and individual physiology. The "optimized" ranges shown reflect our clinical preference for adults pursuing hormone or metabolic optimization, they are not regulatory standards. Talk to a licensed clinician about results that concern you.

Educational purposes only. The Lab Decoder provides educational estimates based on published clinical formulas and peer-reviewed research. It is not medical advice, does not constitute a prescription, and is not a substitute for evaluation by a licensed clinician. All medical decisions, including any treatment, medication, or dosing recommendations, are made exclusively by a U.S. licensed physician after individual patient evaluation through OPTML's intake process.

How this tool calculates

Lab values are interpreted against standard CLIA-certified laboratory reference intervals and published clinical practice guidelines. The tool flags values outside reference ranges and provides educational context drawn from the relevant medical society guidelines (Endocrine Society, ADA, AACE, NAMS).
