Understanding Your Results

A positive or reactive result is reported as detected and indicates the presence of circulating filarial antigen. A negative result is reported as not detected.
Positive/Reactive: Circulating filarial antigen detected. This supports the diagnosis of filariasis in a compatible clinical setting.
Negative/Nonreactive: No circulating filarial antigen detected. If clinical suspicion remains high, repeat testing or use microscopy/PCR.
⚠️ When to Consult a Doctor:

Consult a physician or infectious disease specialist if the test is positive or if symptoms such as limb swelling, recurrent fever, hydrocele, or swollen lymph nodes persist.

Limitations

  • ⚠A negative result does not completely exclude early or low-level infection
  • ⚠The test primarily detects Wuchereria bancrofti antigen and may not reliably detect all Brugia species
  • ⚠Clinical correlation with symptoms and exposure history is required

Risks & Considerations

  • ●Mild pain or bruise at the venipuncture site
  • ●Rarely, fainting or lightheadedness during sample collection

Interfering Factors

  • ●Grossly hemolysed, lipemic, or icteric samples may affect immunochromatography results
  • ●Frozen specimens may produce invalid results
  • ●Recent antifilarial treatment may reduce circulating antigen levels
