Recommendations for patient-specific baseline testing before anesthesia*

Recommendations for patient-specific baseline testing before anesthesia*
Procedure/patient type Test
Injection of contrast dye Creatinine
Potential for significant blood loss Hemoglobin/hematocrit
Likelihood of transfusion requirement Type and screen
Possibility of pregnancy Pregnancy testΔ
End-stage renal disease Potassium level◊
Diabetes Glucose level determination on day of surgery◊
For further information, refer to UpToDate content on preanesthesia evaluation for noncardiac surgery.
* For testing recommendations for disease evaluation refer to UpToDate graphic on diagnostic testing for patients anticipating anesthesia.
¶ Results from laboratory tests within three months of surgery are acceptable unless major abnormalities are present or the patient's condition has changed.
Δ Pregnancy testing is not recommended before the day of surgery unless pregnancy is suspected.
◊ No absolute level of either potassium or glucose has been determined to preclude surgery and anesthesia. The benefits of the procedure must be balanced against the risk of proceeding in a patient with abnormal results.
