FIELD: medicine.
SUBSTANCE: invention refers to parasitology. For the purpose of microfilaria recovery and detection, microscopic preparations are taken by placing a blood sample into a test tube with the anticoagulant K3 EDTA; plasma is separated from formed elements by deposition for 20-24 hours at temperature 4-15°C without centrifugation. A deposits on its plasma border surface forms a funnel at the bottom of which microfilaria are concentrated; liquid plasma 15-20 mcl is sampled from the bottom, mixed with 1% Lugol's solution; smears are prepared that is followed by microxcopic examination and helminth collection.
EFFECT: invention enables reducing the labour input of the microfilaria recovery from blood.
