Performing Laboratory

Billings Clinic Laboratory:  Hematology

Useful For

  • The qualitative detection of Plasmodium antigens circulating in human venous and capillary EDTA whole blood of individuals with signs and symptoms of malarial infection.
  • It is intended to aid in the rapid diagnosis of human malarial infections and to aid in the differential diagnosis of Plasmodium falciparum infections from other less virulent malarial infections.

Profile/Testing Information

Profile Information:
Malaria Rapid Test
Malaria Smear (quantification)
Reflex Tests:
  • % Plasmodium (if Malaria Smear is positive)
  • Plasmodium Confirmation to State Lab (if Malaria Rapid Test and/or Malaria Smear are positive (additional charge)
  • Specimen will be sent to the CDC for additional confirmation if the test is positive at the State Lab (additional charge)


Malaria Rapid Test Interpretation and Reflex Testing:


  • A negative test result does not exclude infection with malaria particularly at low levels of parasitemia.
  • Confirmation testing will be performed.

Pos P. falciparum:              

  • Patient is positive for P. falciparum.
  • Confirmation will be performed

Pos NON P. falciparum:

  • Speciation and confirmation will be performed.

Pos – MIXED:        

  • Patient is positive for P. falciparum protein antigen and possibly another species of Plasmodium.
  • Speciation and confirmation will be performed

All Malaria Rapid results reflex the new Malaria Smear for quantification.

  • None seen (No Malaria parasites seen)
  • P. falciparum (Patient is positive for P. falciparum. Confirmation will be performed)
  • Malaria Species (Non-falciparum malaria species is present. Speciation and confirmation will be performed by a consulting laboratory.)
