Microbiology plays a key role in diagnosing and treating infectious diseases. Relevant samples from tissue, body fluids (blood, urine, faeces, CSF, abscesses, ascites, pleural fluid) are analysed to identify micro-organisms; bacteria, fungi, parasites, viruses. Tests include cultures and microscopy. Molecular and PCR testing methods are highly sensitive and can detect and quantify DNA from micro-organisms. The sensitivity of micro-organisms to therapies (e.g. antibiotics, anti-virals, anti-TB medication) can be tested, for which can detect resistance and inform treatment decisions.

The presence of antibodies to specific organisms (viral/bacterial) can indicate current and/or previous infection or vaccination. In autoimmune conditions the body produces ‘an immune reaction’ to its own organs. Laboratory tests are important in diagnosing these conditions.
