Blood Tests 

Why?

There are numerous tests that can be performed on a single blood sample to diagnose many diseases.

How?

Despite a large number of tests being requested, usually only one sample of blood is required. A very small needle is used to draw a few mls of blood from a vein just under the skin. Usually this is taken from the arm. Anaesthetic cream can be used first if requested but is not generally required. Depending on the tests the results may take from a few hours to several days to be processed.
