Transferase; aspartate amino (AST) (SGOT)
CPT4 code
Name of the Procedure:
Transferase; aspartate amino (AST), also known as Serum Glutamic-Oxaloacetic Transaminase (SGOT).
Summary
The AST (SGOT) test measures the level of aspartate aminotransferase enzyme in the blood. Elevated levels of AST can indicate liver damage or other medical conditions.
Purpose
Medical Condition or Problem It Addresses:
The AST test is primarily used to detect liver damage. It is also helpful in diagnosing conditions related to the heart and muscles.
Goals or Expected Outcomes:
- Identify liver damage or disease.
- Determine the severity and progression of liver conditions.
- Aid in the diagnosis of heart and muscular disorders.
Indications
Symptoms or Conditions:
- Jaundice (yellowing of the skin and eyes).
- Unexplained fatigue.
- Abdominal pain or swelling.
- Nausea and vomiting.
- Symptoms suggestive of liver or heart conditions.
Patient Criteria:
- Individuals with a history of liver disease.
- Patients undergoing treatment that affects liver function.
- Individuals with symptoms indicating muscle or heart issues.
Preparation
- Generally, no significant preparation is required.
- The patient may need to inform the healthcare provider about all medications and supplements they are taking, as some can affect the test results.
Procedure Description
- Blood Sample Collection: A healthcare professional will draw a small amount of blood from a vein in your arm using a sterile needle.
- Laboratory Analysis: The blood sample is sent to a lab where it is analyzed for AST levels.
Tools/Equipment Technology Used:
- Sterile needles.
- Vials for blood collection.
- Laboratory equipment to measure enzyme levels.
Anesthesia or Sedation:
- No anesthesia or sedation is required for the blood draw.
Duration
- The blood draw takes approximately 5-10 minutes.
- Laboratory analysis time varies but typically takes a few hours to a couple of days.
Setting
- The procedure is usually performed at a hospital, outpatient clinic, or diagnostic lab.
Personnel
- A trained phlebotomist or nurse performs the blood draw.
- Laboratory technicians analyze the blood sample.
Risks and Complications
Common Risks:
- Minor bruising or bleeding at the needle site.
- Slight discomfort or pain during the blood draw.
Rare Risks:
- Infection at the puncture site.
Possible Complications:
- Not typically associated with complications.
Benefits
Expected Benefits:
- Accurate detection and monitoring of liver conditions.
- Early identification of heart and muscle disorders.
Realization of Benefits:
- Test results usually available within a few days, helping guide further diagnosis and treatment.
Recovery
Post-Procedure Care:
- Minimal recovery time; patients can resume normal activities immediately.
- Keep the puncture site clean and covered to prevent infection.
Expected Recovery Time:
- Immediate, as there are no significant recovery requirements.
Follow-Up:
- Based on the test results, further tests or treatments may be needed.
Alternatives
- Alanine Aminotransferase (ALT) Test: Another liver enzyme test.
- Bilirubin Test: Measures the amount of bilirubin to evaluate liver function.
- MRI or Ultrasound: Imaging tests for detailed liver examination.
Pros and Cons:
- Blood tests like ALT can be complementary and provide more comprehensive information.
- Imaging tests can offer visual insight but are more expensive and time-consuming.
Patient Experience
During the Procedure:
- You may feel a brief pinch or sting when the needle is inserted.
After the Procedure:
- Mild soreness or bruising at the blood draw site.
- No significant pain or discomfort expected.
Pain Management:
- Over-the-counter pain relievers, if necessary, for any minor discomfort.
