Time of Collection the blood-Examination should be carried out at night.Some specimen for microfilaria during the they also. If midnight blood collection between 10 pm to 02 am.
Materials needed-
                          1. Blood lancet,

                          5. 70% alcohol

1. Sterilize the finger to be pick with ethornal 4th finger of the left hand. Collect the 1st drop of blood because that appears contain more microfilaria.
2. Mixed the blood with sodium citrate solution using the corner of a cover sleep. Cover the preparation with the cover slide.
3.Prepare to thick flim and on another slide using two drops more of blood for the identification of stain microfiliria.
4.Examine the face smare immediately under the 10x objective.
5.The first smare of the blood presents of microfiliria is movement among the red blood cell.

Standing for Microfiliria Slide
Materials needed beker staining Zar 2% acid alcohol. Preparation 2 ml hydrochloric acid mixed with 98 ml alcohol (Mitchell Alcohol)
1.The Hemoglobinison of Microfiliria   slide.Prepare a thick blood smare as meleria parasite smare.
2.The hemoglobinsion of thick smart as malaria parasite slide as a place the slide vertically in the staining tray and through feel with distilled water.
3.Leave for 10 minutes for hemoglobin sink gradually to the bottone. Take the 3 slide 3 and pour off the distilled Water from the slide.
4.Fixed the slide in 2% acid alcohol by one drop only
