General Surgery - Tests Before Surgery
Tests Performed Before Surgery
Many surgeons order routine laboratory tests before admission to the hospital, or even before certain outpatient procedures, to identify potential problems that might complicate surgery if not detected and treated early. According to the US Food and Drug Administration (FDA), some of the most common tests performed before surgery (and possible reasons/symptoms why they are performed) are included in the following list:
- Chest X-rays - may be used to help diagnose causes of shortness of breath, chest pain, cough, fever of unknown origin, and other abnormal heart, respiratory, and lung sounds.
- Electrocardiogram (ECG or EKG)
- Urinalysis - may be used to diagnose kidney and bladder i lso detect drugs present in the body.
- White blood count - may be used to diagnose fever of unknown origin, infection, and use of drugs known to affect white blood counts.
The following tests, used on blood and urine specimens, measure certain substances and electrolytes in the body:
Glucose - helps to identify causes of excessive sweating with tremor or anxiety, muscle weakness, diabetes, pancreatitis, cystic fibrosis, altered mental status, and alcoholism.
Potassium - helps to identify causes of vomiting, diarrhea, congestive heart failure, muscle weakness, tissue damage, hypertension, and diabetes.
Sodium - helps to identify causes of vomiting, diarrhea, excessive sweating, dehydration, pulmonary disease, central nervous system disease, congestive heart failure, and cirrhosis of the liver.
If you have questions or concerns about any of the tests ordered by your physician, and the importance of having them, be sure to address them before having surgery.
