Methodology, units and limitations

AI-collected source-comparison prototype. Not medically reviewed. Not a diagnostic tool. Reference intervals describe a source population; categories and treatment goals have different purposes. Named views do not establish a universal optimum. Country identifies a source, not a biological normal for everyone there.

Source counts use stable publisher IDs; one source may supply several legitimate categories. Source dates and recorded access dates are separate. Older rows explicitly marked not rechecked have not received a new source review. Missing age, fasting, assay and risk details are not inferred.

Strict < and > differ from inclusive ≤ and ≥. Approximate and unknown boundaries are labeled, not converted into exact cutoffs. Printed endpoint precision is preserved; gaps between source categories are not silently filled.

Bars show only the visible portion of each interval. Arrows indicate continuation; small intervals are not enlarged to imply a wider range. Display rounding does not change stored values. Numerically equivalent units do not change the numbers.

Personal-result entry is not available in this release. Do not enter health results into the marker finder. The tool does not classify you, recommend treatment or adjust ranges for your age.
