The LYHER COVID 19 Antigen Rapid Test (Oral Fluid) is a single use in vitro diagnostic device designed for rapid self testing. It detects the presence of the SARS CoV 2 (the virus causing COVID 19) antigen in human oral fluid (saliva) samples for individuals suspected of infection. The test is designed for ease of use, with minimal discomfort, and a simple procedure delivering a result typically within ≈ /15 /minutes. According to the manufacturer, the test uses a colloidal gold immunoassay format, is CE certified, and offers high detection accuracy.
The kit includes: a test cassette, an extraction tube with buffer solution, a dropper, and instructions for use. The specimen is collected from oral fluid (no deep nasal or throat swab required) and the sample is processed and applied to the cassette; after the specified time the result is read. The packaging supports self testing in home or other non laboratory settings.
Non invasive specimen collection – Because the sample is oral fluid (saliva) rather than a deep nasal or oropharyngeal swab, the procedure is more comfortable and easier to self administer, which may improve user compliance.
Fast results – The result is available in approximately 15 minutes, enabling quick decision making.
High accuracy – The manufacturer claims high specificity and sensitivity (for example LYHER’s website cites “high detection accuracy” and “fast result delivery”).
Simple to use, minimal equipment required – No laboratory instrumentation is needed; the test cassette format means it can be used in home or field settings.
Shelf stable and convenient – Storage conditions typically between 2–30 /°C and shelf life up to 24 months (depending on batch) make it practical for stock and logistics.
Supports frequent testing strategy – Because of ease of use and affordability, this kit is suited to regular self checking, helping detect infections early and reduce spread risk
