What’s searchable?Complement C4 — lab reference
Ask your clinician to use performing-lab range and trend.
Immunoglobulin G (IgG) — lab reference
Age and assay-specific. Ask your clinician to consider subclasses or electrophoresis when indicated.
Immunoglobulin A (IgA) — lab reference
Age and assay-specific. Important when interpreting IgA-based celiac testing.
Immunoglobulin M (IgM) — lab reference
Age and assay-specific.
Cytokines, including IL-6 and TNF-α — lab reference
Sample handling and test methods can change a cytokine result. Compare it with the exact range from your lab and ask why the test was ordered.
Prothrombin time (PT) — lab reference
Reagent-specific. Ask your clinician to read this result with INR, liver function, vitamin K, and anticoagulants.
INR — lab reference
Normal range only. Warfarin therapeutic targets are indication-specific.
Activated partial thromboplastin time (aPTT) — lab reference
Reagent-specific. Heparin monitoring may use different targets or anti-Xa.
Fibrinogen — lab reference
Acute-phase reactant; functional and antigenic assays differ.
D-dimer — lab reference
Age-adjusted and assay-specific diagnostic strategies may apply. Not a stand-alone thrombosis diagnosis.
Thrombin time — lab reference
Reagent-specific; affected by heparin, direct thrombin inhibitors, and fibrinogen abnormalities.
