How Our HIV Rapid Test Works

HIV Rapid Test | RapidTest.comPeople who believe that they may have contracted a dangerous disease live with the stress of not knowing until a test has been performed. The HIV Rapid Test from Diagnostic Automation / Cortez Diagnostics, Inc. is designed to give doctors the opportunity to present patients with test results as quickly as possible.

This test works by evaluating the blood of the patient. A specimen of whole blood, serum and plasma must be provided in order for the test to be accurately completed. This specimen is then tested for the presence of HIV antibodies. These antibodies bond with the gold conjugated antigens that are provided in the test kit.

If HIV antibodies are present in the specimen, a red line appears in the test zone to indicate that the individual has tested positive for HIV. The control zone must appear red every time the test is performed. This control indicator is used to increase the accuracy of the test.

An accuracy rate of 99 percent means that patients are able to learn results quickly to determine whether treatment is necessary. Medical professionals have the option to repeat the test in the case of a positive result to ensure that it is not a false positive. The test can also be repeated by a confirmatory test.

Malaria Rapid Test kits

Malaria Rapid test

Malaria is a serious parasitic disease characterized by fever, chills, and anemia and is caused by a parasite that is transmitted from one human to another through the bite of infected Anopheles mosquitoes. There are four kinds of malaria that can infect humans: Plasmodium falciparum, P. vivax, P. ovale, and P. malariae. In humans, the parasites (called sporozoites) migrate to the liver where they mature and release another form, the merozoites. The disease now occurs in more than 90 countries worldwide, and it is estimated that there are over 500 million clinical cases and 2.7 million malaria-caused deaths per year.

At present, malaria is diagnosed by looking for the parasites in a drop of blood. Blood will be put onto a microscope slide and stained so that the parasites will be visible under a microscope.

We offer two formats of the test. One test, the Malaria (Pan-LDH) W/B RapiCard™ InstaTest Cat# 172120-25, can detect all four species of malaria Plasmodium falciparum, Plasmodium vivax, Plasmodium ovale, and Plasmodium malariae. This pan-LDH Antigen Test contains a membrane strip, which is pre-coated with anti-pan LDH monoclonal antibodies on the test line region of the strip. When a Whole Blood specimen is applied at one end of the membrane and following the application of the assay buffer, it reacts with the colloidal gold-anti-pan LDH antibody that has already been applied to the specimen pad. The mixture then migrates chromate-graphically towards the other end of the membrane and reacts with the monoclonal antibodies previously placed on the test line region. If the blood contains one or more of the four Malaria species, a colored line will appear in the test line region, showing a positive result. The absence of the colored line in the test region indicates a negative result; therefore the whole blood does not contain detectable levels of any of the Malaria species.

The other format, Malaria (Pf/Vivax) W/B RapiCard™ InstaTest Cat# 172110-25, will differentiate between the two species: Plasmodium falciparum anf Plasmodium Viavax. This Malaria pf (HRP II) / pv (LDH) Antigen 172110-25 Test contains a membrane strip, which is pre-coated with two monoclonal antibodies as two separate lines across a test strip. One monoclonal antibody (test line 1) is specific to the P. falciparum histidine rich protein-2 (Pf HRP-2) and another monoclonal antibody (test line 2) is specific to the lactate dehydrogenase of the P. vivax species (pvLDH). A Conjugate pad is dispensed with monoclonal antibodies conjugated to colloidal gold, which are specific to P. falciparum histidine rich protein-2 (Pf HRP-2) and specific to the lactate dehydrogenase of P. vivax. Therefore, the antigen of Plasmodium falciparum and Plasmodium vivax can be differentially detected.
