==Other Diagnostic Studies==
===Antigen Detection===
Antigen detection using an [[immunoassay]] for circulating filarial [[antigen]]s constitutes a useful diagnostic approach, because microfilaremia can be low and variable.  A rapid-format immunochromatographic test, applicable to [[Wuchereria bancrofti]] antigens, has been recently evaluated in the field.


===PCR===
==Overview==
Molecular diagnosis using [[polymerase chain reaction]] is available for [[W. bancrofti]] and [[B. malayi]].
There are no additional diagnostic findings for filariasis.  


===Biopsy===
==Other Diagnostic Studies==
Identification of adult worms is possible from [[tissue]] samples collected during nodulectomies ([[onchocerciasis]]), or during subcutaneous biopsies or [[worm]] removal from the [[eye]] (loiasis).
There are no additional diagnostic findings for filariasis.  
 
===Antibody Detection===
Antibody detection is of limited value.  Substantial antigenic cross reactivity exists between filaria and other [[helminth]]s, and a positive [[serologic]] test does not distinguish between past and current [[infection]].
