Journal of Medical Hypotheses and Ideas3Filariasis and serum specific gravity5454VirojWiwanitkit20151005Filariasis is a problematic tropical vector borne infection. Here, the author proposes an idea on a physical change, serum specific gravity, in serum of filariasis cases and further extrapolates for its clinical usefulness.  According to this study, the finalized estimated serum specificity in filariasis is more than that of normal condition. The change of the specific gravity due to additional content or mass can be demonstrated and might be useful for diagnosis and following up of filariasis.https://ijmhi.tums.ac.ir/index.php/ijmhi/article/view/54https://ijmhi.tums.ac.ir/index.php/ijmhi/article/download/54/54
