The purpose of DEC provocation test in filariasis assessment is to:
Show Hint
DEC Provocation = "Provoking" the worms to come out during the day.
Updated On: May 25, 2026
- Destroy adult worms in the body
- Detect antibodies against filarial parasites
- Induce microfilariae in peripheral blood for detection
- Produce immunity against filariasis
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Filariasis diagnosis often depends on detecting microfilariae, which usually exhibit nocturnal periodicity (appearing in blood only at night).
Step 2: Meaning
The DEC (Diethylcarbamazine) provocation test is used when night-time blood sampling is not feasible.
Step 3: Analysis
A small dose of DEC causes the microfilariae to temporarily migrate from the deep pulmonary vessels into the peripheral circulation during the daytime.
Step 4: Conclusion
This facilitates the detection of the parasite during regular clinic hours. Final Answer: (C)
