Preoperative tests

Preoperative tests are tests that are carried out before planned (elective) surgery. They provide information about conditions that may affect the treatment you will need.



 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](/health-library/medical-exams/blood-gases-test)
-   a blood glucose test
-   a urine dipstick test
-   kidney function tests
-   a [sickle cell](/health-library/conditions/sickle-cell-anaemia) test
-   a \[pregnancy test] (for women)
-   lung function tests
-   a chest [X-ray](/health-library/medical-exams/x-ray)
-   an electrocardiogram (ECG)
