Question | Answer |
---|---|
BACTERIAL STUDIES | Antinuclear Antibody (ANA); Antistreptolysin O (ASO) titer; Cold Agglutinins; Febrile Agglutinins; FTA-ABS; Rapid plasma reagin (RPR); Rheumatoid factor (FR) |
VIRAL STUDIES | Anti-HIV; Cytomegalovirus antibody (CMV); Epstein-Barr virus (EBV); Hepatitis B surface antigen (HBsAg) |
GENERAL STUDIES | C-reactive protein (CRP); Human chlorionic gonadotropin (HCG) |
Antinuclear Antibody (ANA) | positive results in autoimmune disorders, specifically systemic lupus erythematosus |
Antistreptolysin O (ASO) titer | to demonstrate infection from streptococcus bacteria (strep throat) |
Cold Agglutinins | present in cases of atypical pneumonia |
Fever Agglutinins | presence of antibodies to specific organisms indicates disease condition (i.e. tularemia) |
FTA-ABS | fluorescent treponemal antibody absorption test, confirmatory test for syphilis (when done on older people, its usually testing for neural syphilis) |
Rapid Plasma Reagin (RPR) | positive screen indicates syphilis; positives need to be confirmed |
Rheumatoid Factor (RF) | presence of antibody indicates rheumatiod arthritis |
Anti-HIV | human immunodeficiency virus is screened |
Cytomegalovirus antibody (CMV) | confirmation test |
Epstein-Barr virus (EPV) | presence of this heterophil antibody indicates infectious mononucleosis |
Hepatitis B surface antigen (HBsAg) | demonstrates the presence of hepatitis antigen on the surface of the red cells |
C-reactive protein (CRP) | increased levels in inflammatory conditions |
Human chorionic gonadotropin (HCG) | present in pregnancy (serum & urine); can also be used in determining certain cancers (testicular) in men |
