Intended Use

The Malaria Rapid Test is a lateral flow chromatographic immunoassay for the simultaneous detection and differentiation of Plasmodium falciparum (Pf) antigen and P. vivax, P. ovale, or P. Malariea antigen in whole blood.

This device is intended to be used as a screening test and as an aid in the diagnosis of infection with Plasmodium. Any reactive specimen with the Malaria Rapid Test must be confirmed with alternative testing method(s) and clinical findings.

Summary and Explanation of the Test

Malaria is a mosquito-borne, hemolytic, febrile illness that infects over 200 million people and kills more than 1 million people per year. It is caused by four species of Plasmodium: P. falciparum, P. vivax, P.ovale, and P. malariae. These plasmodia all infect and destroy human erythrocytes, producing chills, fever, anemia, and splenomegaly.

P. falciparum causes more sever disease than the other plasmodial species and accounts for most malaria deaths. P. falciparum and P. vivax are the most common pathogens, however, there is considerable geographic variation in species distribution1. Traditionally, malaria is diagnosed by the demonstration of the organisms on Giemsa stained smears of peripheral blood, and the different species of plasmodium are distinguished by their appearance in infected erythrocytes1. The technique is capable of accurate and reliable diagnosis, but only when performed by skilled microscopists using defined protocols 2, which presents major obstacles for the remote and poor areas of the world.

The Malaria Rapid Test is developed for solving these above obstacles. It detects the antibodies generated in serum or plasma in response to the infection of plasmodium. Utilizing the Pf. specific antigen (HRP-II) and pan-malaria antigen (aldolase), the test enables simultaneous detection and differentiation of the infection of P.falciparum and or P. vivax, ovale, and malariae3-5, by untrained or minimally skilled personnel, without laboratory equipment.

Reagents and Materials Provided

1. One pouch sealed with desiccant

2. Blood diluent buffer in a dropper bottle

3. One package insert

Materials Required But Not Provided

1. Clock or Timer

2. Lancing device for whole blood test

Sample Collection and Preparation

Whole Blood

Drops of whole blood can be obtained by either finger tip puncture or veinpuncture. Do not use any hemolyzed blood for testing.

Whole blood specimens should be stored in refrigeration (2°Ċ-8 °Ċ) if not tested immediately. The specimens must be tested within 24 hours of collection.

Test specimens as soon as possible after collecting. Store specimens at 2 to 8℃ if not tested immediately.

Store specimens at 2 to 8℃ up to 5 days. The specimens should be frozen at -20℃ for longer storage.

Avoid multiple freeze-thaw cycles. Prior to testing, bring frozen specimens to room temperature slowly and mix gently. Specimens containing visible particulate matter should be clarified by centrifugation before testing.

Interpretation of Result

Negative: If only the C band is present, the absence of any burgundy color in the both T bands (T1 and T2) indicates that no plasmodium antigens are detected. The result is negative.

Positive: Pf positive: In addition to the presence of C band, if only T2 band is developed, the test indicates for the presence of pHRP-II antigen. The result is Pf positive.

Pan positive: In addition to the presence of C band, if only T1 band is developed, the test indicates for the presence of pLDH antigen. The result is either Pv, Pm, or Po positive.

Mixed positive: In addition to the presence of C band, both T1 and T2 bands are developed, the test indicates for the presence of both pHRP-II and pLDH. The result is positive.

Note: Samples with positive results should be confirmed with alternative testing method(s) and clinical findings before a positive determination is made.

Invalid: If no C band is developed, the assay is invalid regardless of any burgundy color in the T bands as indicated below. Repeat the assay with a new device.

Storage

Store the test kits at temperature 4-30°C,in the sealed pouch for the duration of the shelf life (24 months).

Warning and Precautions

1. For in-vitro diagnostic use only

2. All patient samples should be treated as if capable of transmitting disease.

3. Do not interchange reagents from different lots. Do not use it beyond expiration date.
