A Dipstick Test for Rapid Diagnosis <strong>of</strong> Russell’s<br />

Viper (Daboia russelii siamensis) Bite (A 20<br />

minute Russell’s viper dipstick)<br />

OBJECTIVES<br />

Aye-Aye-Myint, Tun-Pe <strong>and</strong> Tin-Zar-Maw<br />

Venom <strong>Research</strong> Laboratory,Department <strong>of</strong> Medical <strong>Research</strong> (Lower Myanmar)<br />

• To develop a robust rapid test for diagnosis <strong>of</strong> Russell’s viper bite<br />

• To select <strong>and</strong> estimate antivenom doses required for treating the case<br />

RATIONALE<br />

• Russell’s viper bite is an occupational hazard <strong>of</strong> our farmers.<br />

• Only 44% <strong>of</strong> the victims brought dead snakes for identification.<br />

• 28% <strong>of</strong> the victims are not envenomed.<br />

• 50% <strong>of</strong> non envenomed cases are given 1-4 ampoules <strong>of</strong> antivenom.<br />

• At present- selection <strong>of</strong> antivenom for treating snakebite cases is based on:<br />

• If snake is brought -species identification<br />

• If no snake is brought -syndromic approach plus circumstances <strong>of</strong> the bite<br />

• A rapid diagnostic test is required for:-<br />

- Identification <strong>of</strong> inflicting snake<br />

- Selection <strong>of</strong> an appropriate antivenom<br />

- Estimation <strong>of</strong> antivenom dose<br />

- Minimize wastage <strong>of</strong> expensive antivenom<br />

• A rapid enzyme immunoassay dipstick test developed<br />

- needs to use expensive reagents<br />

- takes 40 minutes to get the result.<br />

• A less expensive <strong>and</strong> more rapid diagnostic test is urgently needed.
