Loop-mediated Isothermal Amplification
The procedure of the LAMP test is similar to that of PCR but instead of using various temperatures like PCR, LAMP uses a constant temperature.
What does the test find?
The swabs from your nose and throat are used to convert the viral RNA sample to DNA and then multiple copies are made using LAMP technology and with the use of chemical reagents and fluorescent dyes, if the sample is positive, the result is a cloudy mixture.
Samples are collected in the form of the throat or nasal swabs. Another way is using coughed up mucus as a sample.
Specificity & Sensitivity
Similar to RT-PCR and PCR, the LAMP results are also highly sensitive. LAMP can only detect if the individual has the virus at present it can not detect if someone has recovered from the virus or if the virus is active or not.
