Mansonella species microfilariae do not exhibit any periodicity and therefore a random blood draw is acceptable.

Blood should be obtained and examined every 8 to 12 hours for 2 to 3 days before excluding infection. 24032016 Human filarial nematode worms have complicated lifecycles which primarily consists of five stages.

Adult worm may be found in fluids drawn from swollen areas or serous collections.

This slide is then examined under an electron microscope to check for the presence of parasitic larval roundworms. A popular diagnostic procedure involves blood being drawn from a larger vein and smeared on a glass slide. Patients are usually given Florocid injections to help effectively combat infection.
