LOINC Code 76490-2: IgG (U) [Moles/Vol]
76490-2 is a LOINC code used to identify IgG (U) [Moles/Vol] in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component IgG. It is commonly used with the system or sample type Urine.

What it does not mean
- The code identifies the observation or test, not the actual result.
Key facts
- IgG [Moles/volume] in Urine
- IgG
- Urinary IgG is used in combination with urinary albumin to distinguish selective vs. unselective forms of tubular proteinuria (that is, increased urine excretion of high-molecular-weight plasma proteins such as IgG in comparison to albumin) as IgG is markedly elevated only in unselective forms of glomerular proteinuria. Urinary IgG can also monitor and assess glomerular proteinuria. This term was created for, but not limited in use to, the cobas, Tina-quant IgG Gen.2 test kit.
