The government has been under fire for several days now about the rate of testing for Coronavirus, especially among front-line heath workers.
Currently there are two types of test available.
The first is a swab test, which is sent to a Public Health England laboratory for analysis.
However results can take 48 hours to come back, are only about 70% reliable.
This type of test will only indicate if a person has the disease right now.
The second is is an antibody test – similar to pregnancy test kit.
It requires a drop of blood from a finger-prick and within 15 minutes or so lines will show on the test if a person is or has been infected with Covid-19, and their body has built up an immunity to it.
Doctors say antibody tests are vital in the NHS front-line fight against the spread of the disease.
