[Ans] which is the best time to have blood test for filariasis

Step 1 : Introduction to the question "which is the best time to have blood test for filariasis"

These are spread by blood-feeding black flies and mosquitoes. This disease belongs to the group of diseases called helminthiases. Eight known filarial nematodes use humans as their definitive hosts. These are divided into three groups according to the niche they occupy in the body:

Blood must be drawn at appropriate times, which reflect the feeding activities of the vector insects. Examples are W. bancrofti, whose vector is a mosquito; night is the preferred time for blood collection. Loa loa's vector is the deer fly; daytime collection is preferred. This method of diagnosis is only relevant to microfilariae that use the blood as transport from the lungs to the skin.

The adult worms, which usually stay in one tissue, release early larval forms known as microfilariae into the host's bloodstream. Individuals infected by filarial worms may be described as either "microfilaraemic" or "amicrofilaraemic", depending on whether microfilariae can be found in their peripheral blood. .Occult filariasis is diagnosed in amicrofilaraemic cases based on clinical observations
