Preoperative tests

Preoperative tests are carried out before planned (elective) surgery. They provide information about conditions which may affect treatment.

Tests you need to have before your operation depend upon:

  • your age
  • your overall health
  • medications you are taking
  • the type of surgery you are having

Tests can include:

  • a full blood count (FBC)
  • blood clotting tests
  • a blood gases test
  • a blood glucose test
  • a urine dipstick test
  • kidney function tests
  • a sickle cell test
  • a [pregnancy test] (for women)
  • lung function tests
  • a chest X-ray
  • an electrocardiogram (ECG)
