Intended Use

Advantage PAN Malaria Card is a rapid, visual and sensitive immunoassay for the qualitative diagnosis of all four Plasmodium Species (P.falciparum/P.vivax/P.malariae/P.ovale) based on pLDH antigen in human whole blood only.

Salient Features

  • Detects infection with Plasmodium species(P.falciparum/P.vivax/P.malariae/P.ovale)
  • Excellent Sensitivity & Specificity as per WHO Malaria RDTs Evaluation.
  • See through Device for easy result interpretation.
  • Longer shelf life -30 months, storage at 4-30° C.
  • Results within 20 minutes.

Principle

Advantage PAN Malaria Card is an immunoassay based on the “Sandwich principle”. The method uses monoclonal anti-pan specific pLDH(plasmodium lactate dehydrogenase) antibody conjugated to colloidal gold and another monoclonal anti-pan specific pLDH antibody immobilized on a nitrocellulose strip in a thin line. The test sample is added in the sample well ‘A’, followed by addition of Assay buffer in Buffer well ‘B’. If the sample contains P.falciparum/P.vivax/P.malariae/P.ovale, the colloidal gold conjugate complexes the Pan specific pLDH in the lysed sample. This complex migrates through the nitrocellulose strip by capillary action. When the complex meets the line of the corresponding immobilized antibody, the complex is trapped forming a purplish pink band which confirms a reactive test result.Absence of a colored band in the test region indicates a non-reactive test result. To serve as a procedural control an additional line of anti-mouse antibody has been immobilized on the strip as control.

Evaluations

(i) WHO Evaluation:

The Advantage PAN Malaria Card test kit has been evaluated by WHO, Geneva using a panel of wild & cultured malaria positive sample and the results obtained are as follows :

Panel Detection Score* Specificity*
200 Parasites 77.0% (P.f) and (P.v)
2000 Parasites 98.0% (P.f) and 100.0% (P.v)
Negative Samples 96.6 %*

(ii) In-house Evaluation
Analytical Sensitivity: The test can detect parasitemia levels of >100 parasites per µl of blood for P. falciparum (pLDH) and P. vivax (pLDH) The Advantage PAN Malaria Card has been evaluated in-house with malaria positive and negative clinical whole blood samples and compared with microscopic examination. The evaluation also included cross-reacting samples; Dengue, Rheumatoid factor, Leptospira, HIV, HCV, HBV, M. tuberculosis, Syphilis, Brucella, Scrub typhus positive samples. The results obtained are as follows:

Sample No. Of Samples tested Advantage PAN Malaria Card Sensitivity Specificity
Positive Negative
Malaria Negative 2010 1 2009 99.95
Cross-reacting sample 59 0 59 100
P.falciparum Positive 58 58 0 100
P.vivax Positive 105 105 0 100

Precision : Within-run and between-run precisions have been determined by testing 10 replicates of 8 specimens: four negative and four positive; two weak and two moderate positive. The C.V (%) of negative, moderate positive and weak positive samples were within 10% of the time.
