This test is uesed for teh detection of Plasmodium (malaria), Babesia, trypanosomes and microfilaria.

  
EDTA whole blood + 3 thin and 3 thick blood smears
  
  
  • Although the optimum time of collection is about midway between chills, to ensure obtaining stages on which species identification can be made, blood collection for Malaria/parasite smears should be performed immediately upon the first suggestion of Malaria.
  • Since single films may not reveal organisms, successive films at 6, 12, or 24 hours are sometimes necessary.
  • Blood samples must be taken before any antimalarial drugs are used to ensure demonstration of organisms if the patient does have malaria.
  

Do not spin

Blood Smears must be made within 1/2 hour of collection

Blood smears for Malaria and other blood parasites :

Hospitals

  • Blood should be immediately delivered to the laboratory for slide preparation.

Clinics with laboratory services

  • Prepare slides according to the instructions below, and submit along with the collection tube.

Clinics without a laboratory and Patient Service Centers

  • Transport the specimen to Allina Health Laboratory Central lab by courier.
  • The specimen must arrive within 4 hours of collection.
    • A rush courier may be required to meet this requirement.

SMEAR PREPARATION:

  • Make smears within 30-60 minutes of collection if possible.

Thick smears (prepare 4):

  • Place 1-2 drops of blood on a slide.
  • Using the corner of another slide, stir the blood in a circular motion for about 30 seconds to prevent the formation of fibrin strands.
  • Spread the blood out to an area about the size of a nickel. Thick films need to be thin enough to read newsprint through them.
  • Label each slide with the patient's name, a second unique identifier and the date and time of collection.
  • Allow the slides to air dry.

Thin smears (prepare 4):

  • Place a small drop of blood near one end of a slide.
  • Spread the blood over the surface with the edge of a second slide to form a thin layer, in the same manner that is used to prepare a smear for hematology.
  • Label each slide with the patient's name, a second unique identifier and the date and time of collection.
  • Allow the slides to air dry.
