Specimen: Serum
Fasting: Not stated
LOINC: 40678-5

Laboratory assay overview

T. gondii IgM is typically detected within a few days of infection, peaks within a few weeks, and usually falls to undetectable levels within a few months. In some patients, however, T. gondii IgM persists for more than a year; Thus, detection of T. gondii IgM does not necessarily indicate recent or ongoing toxoplasmosis.

We compile every detail above directly from named laboratory directories and published clinical studies. Laboratories calculate standard reference intervals from the statistical distribution of tested populations for a specific assay method and demographic group, rather than setting universal optimal targets.
