According to a new study, the result of the coronavirus test done at home is exactly the same as the test done in clinics. These coronavirus test home kits consist of self-swabs.

Accuracy of self-swab kits

Researchers have found that these self-swab kits give the least false COVID-19 positive results in people who do not have a high viral load. This is not a big drawback as these self- swab kits give only a 2% false-negative result. According to a study published in Jama Network Open, 185 participants of the team distributed self-switched kits.

Self-swab kits are mid nasal in nature. They are inserted into the nose up to an inch, while the clinic swabs are nasopharyngeal. It is carefully inserted into the nasopharyngeal opening. About 22% of the volunteers tested positive. These home mid nasal swabs were later compared with clinically collected samples. It is found that home swabs have a symptom detecting sensitivity rate of 80%. This means that these swabs can identify more than three-quarters of positive cases. The accuracy rate of these swabs is 95% in people with high viral load.





Specificity rate of home kits

The specificity of home swab tests is 97.9%. That is, they have very few false negativities. Researchers believe that the specificity of these swabs is lower in patients with low viral load. In addition, some people performed self-swab tests at home after testing at the clinic, resulting in a very low viral load.

Tests at home lower overall risk factors

Researchers have found that these self-swab kits will impart a range of benefits by decreasing an overall range of hazardous factors. First of all, an infected person will become able to test himself by staying at home. In this way, he will not spread any pollutants in the environment. Furthermore, this technique will save the time of making an appointment and going through the entire diagnosis process.

Secondly, by conducting self-swab tests, the carrier will not come in contact with health care providers. This move will ensure the safety of maximum health care providers.
