Selecting a rapid antigen test that provides an accurate and trustworthy result early provides peace of mind and is the only way to stop potential transmission of Covid-19.
Covid-19 rapid antigen tests should have an analytical sensitivity (Level of Detection) of under 50 TCID accompanied with a Ct value which states the number of copies of virus per mL.
The Limit of Detection (LoD) is the lowest concentration of an analyte in a sample that can be consistently detected. The most important thing is that the lower the LoD, the better the rapid test. A low LoD means the test will pick up the smallest trace of infection within the sample taken, meaning the infection will be picked up early.
Gardian T3 Covid-19 Rapid Antigen Tests have a LoD of 10, and unlike other rapid tests can detect infection as early as day one.
