==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]].
