Anaplasma phagocytophilum (HGA) Antibody, IgG
Use
This test is designed to detect the presence of IgG antibodies to Anaplasma phagocytophilum (HGA). A positive result, indicated by an antibody titer equal to or greater than 1:80, suggests a recent or past infection with the organism. Anaplasma phagocytophilum is the causative agent of human granulocytic anaplasmosis (HGA), a tick-borne disease. Detection of IgG antibodies indicates an immune response to the pathogen, suggesting exposure or infection history.
Special Instructions
Parallel testing is preferred. Convalescent specimens must be received within 30 days from receipt of acute specimens, and specimens should be marked clearly as 'acute' or 'convalescent.'
Limitations
The test's performance characteristics have been determined by ARUP Laboratories and have not been cleared or approved by the FDA. As it is a Laboratory Developed Test (LDT), it is intended for clinical purposes within a CLIA certified environment. The test is sensitive to potential quality issues like bacterial contamination, hemolysis, lipemia, and turbidity, which can cause rejection of the specimen.
