What does this converter do?

This tool converts anti-thyroglobulin antibody values between IU/mL, kIU/L, and IU/L. The conversion is specific to results reported in international units and should not be applied to arbitrary assay-specific units unless the laboratory states equivalence.

Supported units

IU/mL · common reporting kIU/L · equivalent IU/L · alternative

Conversion formulas

kIU/L = IU/mL
IU/L = IU/mL × 1000
IU/mL = IU/L ÷ 1000

Example conversion

If ATG = 100 IU/mL, then ATG = 100 kIU/L and 100,000 IU/L.

Important laboratory note

Anti-thyroglobulin antibody reference ranges and positivity thresholds vary by assay platform and laboratory. This converter only changes units and does not diagnose autoimmune thyroid disease.
