Given the need for data for a rapid, point-of-care cryptococcal antigen (CRAG) lateral flow immunochromatographic assay (LFA), we assessed diagnostic performance of cerebrospinal fluid (CSF) culture, CRAG latex agglutination, India ink microscopy, and CRAG LFA for 832 HIV-infected persons with suspected meningitis during 2006 . Rapid Test (1) Reaction Card for Staphylococcus aureus Test Kit . Finally, interpret the result. rapid and early detecon is essenal. Now, add 40 µL (1 drop) of the patient specimen to the tube. CrAg can be detected using rapid antigen tests. If Cryptococcus antigen is present in the specimen, it binds to the gold-conjugated, anti-Cryptococcus antigen antibodies. CrAg) of Aim: To evaluate the usefulness of Lateral Flow Assay (LFA) for rapid detection of Cryptococcal Antigen (CrAg) from Cerebrospinal Fluid (CSF) sample.

Cryptococcal meningitis is common in sub-Saharan Africa. The advanced HIV rapid diagnostic tests such as determine TB urine lipoarabinomannan lateral ow assay (urine LAM), urine X-pert MTB/RIF assay (urine X-pert), and serum/blood cryptococcal antigen test (serum CrAg) are recommended but frequently not available in many resource-limited set-tings. The membrane was immobilized with anti Cryptococcal monoclonal antibody on the test region. Objective: To determine the sensitivity and specificity of 2 POC lateral flow cryptococcal serum antigen tests, CrAg LFA (Immy, Norman, OK) and the CryptoPS (Biosynex, Strasbourg, France) for diagnosis of cryptococcosis in dogs and cats, using the cryptococcal antigen latex agglutination system (CALAS) as the reference standard. Detection of Cryptococcal Antigens (CrAg) has been the primary method for laboratory diagnosis . The Cryptococcus antigen (CrAg) Lateral Flow Assay has been developed to overcome these issues.

The two were equivalent in their ability to remove interference factors; however, the enzymatic method generally yielded higher titers. Cryptococcal antigen screening by lay cadres using a rapid test at the point of care: A feasibility study in rural Lesotho Fernanda Rick 1, Aline Aurore Niyibizi1, Amir Shroufi *, Kazumi Onami2 . The tests are not recommended for children under 5 years because if the test is not carried out by a healthcare provider the swab can injure their nose. The latex agglutination test for Cryptococcus neoformans antigen is a simple and rapid procedure for the diagnosis of cryptococcal meningitis.
