This test can only be taken at the below location

For this test, you will be required to visit The Doctors Laboratory in London to collect your sample as the sample is not suitable for posting.
 
A number of our tests require the sample to be taken directly at the lab.  This is due to the test's sensitive nature and means the lab needs to store your sample in the right conditions quickly, before beginning analysis.
