Malaria is a curable disease if the patients have access to early diagnosis and prompt treatment.Antigen-based rapid diagnostic tests have an important role at the periphery of health services capability because many rural clinics do not have the ability to diagnose malaria on-site due to a lack of microscopes and trained technicians to evaluate blood films.
Immunochromatographic tests (also called: Malaria Rapid Diagnostic Tests, Antigen-Capture Assay or "Dipsticks") have been developed, distributed and fieldtested. These tests use finger-stick or venous blood, the completed test takes a total of 15–20 minutes, and the results are read visually as the presence or absence of colored stripes on ...
Peripheral blood films stained with Giemsa stain are a method of blood examination used to diagnose the presence of Plasmodium malariae, and detect quartan fever. [5] Rapid diagnostic tests can detect the antigens which cause malaria, a sample of blood is collected from the patient and placed on a test card. After 15–20 minutes bands show up ...
The device is capable of detecting malaria parasites in red blood cells for diagnostic purposes. [3] [4] [5] The device is being tested for use in hospitals, clinics and medical laboratories. The goal is to create Point-of-care-testing (POCT) opportunities in rural areas that lack healthcare access. [1]
Malaria is usually confirmed by the microscopic examination of blood films or by antigen-based rapid diagnostic tests (RDT). Microscopy—i.e. examining Giemsa-stained blood with a light microscope—is the gold standard for malaria diagnosis. [48]
A COVID-19 Rapid Antigen test(top) with a Covid-19 Rapid Antigen and a Influenza A&B Rapid Antigen Test(bottom) A rapid antigen test (RAT), sometimes called a rapid antigen detection test (RADT), antigen rapid test (ART), or loosely just a rapid test, is a rapid diagnostic test suitable for point-of-care testing that directly detects the presence or absence of an antigen.
Of the Romanowsky-type stains, the Giemsa stain is especially important in the detection and identification of malaria parasites in blood samples. [5] [15] Malaria antigen detection tests are an alternative to the staining and microscopic examination of blood films for the detection of malaria. [5]
Similarly, pulse oximetry can test arterial oxygen saturation in a quick, simple, noninvasive, affordable way today, but in earlier eras this required an intra-arterial needle puncture and a laboratory test; and rapid diagnostic tests such as malaria antigen detection tests or COVID-19 rapid tests that rely on a state of the art in immunology ...
