==Overview==
There are no additional diagnostic findings for filariasis.
 
==Other Diagnostic Studies==
==Other Diagnostic Studies==
===Antigen Detection===
There are no additional diagnostic findings for filariasis.  
Antigen detection using an immunoassay for circulating filarial antigens 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===
Molecular diagnosis using polymerase chain reaction is available for W. bancrofti and B. malayi.
===Biopsy===
Identification of adult worms is possible from tissue samples collected during nodulectomies (onchocerciasis), or during subcutaneous biopsies or worm removal from the eye (loiasis).
===Antibody Detection===
Antibody detection is of limited value.  Substantial antigenic cross reactivity exists between filaria and other helminths, and a positive serologic test does not distinguish between past and current infection.
