Organic acids; total, quantitative, each specimen
CPT4 code
Name of the Procedure:
Organic Acids; Total, Quantitative, Each Specimen
Summary
This procedure involves testing a sample (usually urine) to measure the levels of various organic acids. It helps in diagnosing certain metabolic disorders and conditions where abnormal levels of organic acids are present, indicating potential metabolic dysfunction.
Purpose
The primary goal of this procedure is to identify and quantify organic acids in the body to help diagnose metabolic disorders, such as inborn errors of metabolism, nutrient deficiencies, and the effects of certain medications. The expected outcome is a detailed profile of organic acids that can guide further treatment and management strategies.
Indications
- Unexplained metabolic symptoms (e.g., lethargy, developmental delay, recurrent vomiting)
- Suspected metabolic disorders, such as mitochondrial dysfunction or inborn errors of metabolism
- Monitoring the metabolic impact of nutritional interventions or medications
Preparation
- Patients are typically required to collect a urine sample, often the first morning void.
- Some tests may require fasting overnight.
- Certain medications might need to be paused, as instructed by the healthcare provider.
- Ensure proper hydration unless advised otherwise.
Procedure Description
- Sample Collection: The patient collects a urine sample, typically in a sterile container provided by the lab.
- Lab Analysis: The collected sample is sent to the laboratory, where it is analyzed using techniques such as gas chromatography-mass spectrometry (GC-MS).
- Quantification: Various organic acids are quantitatively measured and compared to reference ranges.
Duration
- Sample collection: A few minutes.
- Lab analysis: Several days to a week for results.
Setting
- Typically performed in a clinical laboratory after sample collection at the patient's home or a healthcare facility.
Personnel
- Involves healthcare professionals like lab technicians, pathologists, and the ordering physician.
Risks and Complications
- No significant risks or complications are associated with the procedure as it involves only urine sample collection.
- Rarely, improper sample collection can lead to inaccurate results.
Benefits
- Accurate diagnosis and monitoring of metabolic disorders.
- Guides personalized treatment plans.
- Non-invasive and relatively quick to perform.
Recovery
- No recovery time needed as the procedure is non-invasive.
- Follow-up appointments may be scheduled to discuss results and treatment options.
Alternatives
- Blood tests for metabolic markers.
- Genetic testing for specific metabolic disorders.
- Clinical assessment based on symptoms.
Patient Experience
- Simple and painless urine collection process.
- Minimal discomfort or inconvenience.
- Results may necessitate further diagnostic tests or lifestyle changes, depending on findings.
By providing a detailed profile of organic acids in the body, this test can play a crucial role in diagnosing and managing metabolic disorders effectively.
