The Microbiology laboratories at Homerton University Hospital provide a 24-hour quality diagnostic, interpretative and clinical service.
This Microbiology service consists of therapeutic drug monitoring (TDM), screening for Chlamydia trachomatis, Neisseria gonorrhoeae, enteric infection, Cl difficle and Tb using molecular diagnostic assays
as well as a full complement of tests for bacterial and fungal culture.
The bacteriology section deals with the isolation and identification of microorganisms (bacteria and fungi) obtained from various sites using specimens such as wound swabs, faeces, urine, respiratory specimens and other body fluids eg blood and cerebrospinal fluid. Potential pathogens are identified and, if appropriate, tested for susceptibility to antimicrobial agents.
The department also performs antibiotic assays. Direct microscopy may also be carried out on specimens to examine for bacteria (eg CSF), parasites (eg faeces), cells (eg urine).
Nucleic acid detection is also available with a Molecular laboratory offering specialist diagnostic testing.
Clinical Biochemistry examines serum samples by various automated and manual techniques for the presence of antibodies and antigens on behalf of Microbiology using the Abbott Architect systems. Specimens (eg blood, swabs, faeces) may also be referred for viral culture or further serological testing.
Microbiology works closely with infection prevention and control and the clinical infection directorate in the control and prevention of infectious disease.
The consultant microbiologists provide clinical advice to health care workers on the diagnosis, monitoring and treatment of infections, and are part of the infection prevention and control team.
