Clinical Biochemistry

Clinical Biochemistry measures a wide range of substances in bodily fluids, predominantly blood (serum or plasma), urine and cerebrospinal fluid.

A 24 hour, 7 day acute core clinical biochemistry service is provided on all Imperial College, Chelsea and Westminster and the Hillingdon Hospitals trust sites.

Clinical scientists or medical doctors are available as the Duty Biochemist on site during the working day to provide advice about the selection of appropriate tests and their interpretation.

Biochemistry tests are used to investigate or monitor:

  • major organ function (liver, kidney, bones, heart, muscles)
  • diabetes
  • hormones
  • malignancies
  • proteins
  • drugs.

The majority of these core clinical biochemistry tests are fully automated, although some are manual investigations.
