Fibrinolytic factors and inhibitors; plasminogen, except antigenic assay
CPT4 code
Name of the Procedure:
Fibrinolytic Factors and Inhibitors; Plasminogen (Functional Assay)
Summary
This test measures the functional level of plasminogen in the blood, which is a protein involved in breaking down blood clots. It helps assess how well your body's fibrinolytic system is working.
Purpose
The test is used to diagnose conditions related to abnormal blood clotting or bleeding. It helps determine if there's a deficiency or dysfunction in plasminogen, which can affect your body's ability to manage clots.
Indications
- Unexplained blood clots
- Excessive or unusual bleeding
- Family history of clotting disorders
- Monitoring blood-thinning therapy
Preparation
- Fasting may not be required.
- Inform your doctor about any medications you're taking, as some can affect the results.
- No specific diagnostic tests are required beforehand.
Procedure Description
- A healthcare provider will clean the area around a vein in your arm.
- A needle will be inserted to draw a blood sample.
- The sample is sent to a lab, where it's analyzed to measure plasminogen activity.
- No anesthesia or sedation is required.
Duration
The blood draw takes about 5-10 minutes. Lab results typically come back within a few days.
Setting
The procedure is performed in a hospital, outpatient clinic, or a laboratory.
Personnel
- Phlebotomist or nurse for the blood draw.
- Laboratory technicians and possibly a pathologist for analysis.
Risks and Complications
- Minimal risk of infection or bruising at the puncture site.
- Rarely, a hematoma might form.
Benefits
The test helps diagnose or rule out clotting disorders, allowing for appropriate treatment plans. Results can be used to monitor ongoing treatment effectiveness.
Recovery
- No significant recovery time is needed.
- You can resume normal activities immediately after the procedure.
- Follow-up appointments may be scheduled to discuss results with your doctor.
Alternatives
- Other blood tests for different clotting factors.
- Imaging studies to detect clots.
- Genetic testing if a hereditary disorder is suspected.
Patient Experience
- You might feel a slight prick or pressure when the needle is inserted.
- Minor discomfort or bruising at the puncture site is possible.
- Pain management is usually not necessary, but applying a cold compress can alleviate any discomfort after the procedure.
