HOMOCYSTEINE - URINE in Sri-nagar, Bangalore

Homocysteine – Urine: Price, Purpose, Range & Reports 

Test Overview

The Homocysteine – Urine test is a specialised biochemical assay used primarily to measure the concentration of the amino acid homocysteine excreted in the urine. This measurement is a critical diagnostic tool, often performed after elevated homocysteine levels are found in the blood plasma, to screen for and confirm the diagnosis of Homocystinuria, a rare inherited metabolic disorder.

Homocystinuria is characterised by a defect in the body's ability to metabolise methionine, leading to the accumulation of homocysteine. Identifying this condition requires accurate quantification of homocysteine in biological fluids. If you are searching for the Homocysteine – Urine test price or a reliable lab near me, Apollo 24|7 offers access to accredited diagnostic services for this specialised testing, with secure and timely report delivery.

What is the Homocysteine – Urine Test?

The Homocysteine – Urine test is a quantitative biochemical assay used to measure the amount of the amino acid homocysteine and its related metabolites excreted over a period (usually a 24-hour collection, though sometimes a random sample is used). This test serves as a crucial confirmatory step when preliminary screening tests, such as plasma homocysteine measurements, suggest an underlying metabolic error.

Unlike the more common blood test, the urine test provides evidence of excessive renal clearance of homocysteine, which is highly characteristic of severe metabolic disorders like Homocystinuria. The test utilises advanced analytical techniques like High-Performance Liquid Chromatography (HPLC) or Tandem Mass Spectrometry (MS/MS) to ensure accurate and sensitive measurement of this critical metabolic marker.

What is the Homocysteine – Urine Price?

The cost of the Homocysteine – Urine test reflects its status as a highly specialised biochemical test, requiring complex analytical instrumentation and expert interpretation, particularly when screening for rare genetic disorders.

Factors Affecting the Test Cost

The final price is influenced by these essential quality and service factors:

• Specialised Technology: The assay requires advanced analytical equipment (HPLC or MS/MS) for accurate separation and quantification of homocysteine metabolites, which contributes significantly to the operational cost.
• Sample Collection Complexity: If a 24-hour collection is required, the price factors in the necessary collection containers, stability chemicals, and patient instruction support.
• Specialised Interpretation: The fee covers processing at NABL-accredited Apollo laboratories, ensuring the results are verified by specialised biochemists accustomed to interpreting rare metabolic data.
• Location: Prices may differ slightly between cities due to regional operating costs and logistics.

What is the Purpose of the Homocysteine – Urine Test?

The primary purpose of the Homocysteine – Urine test is to provide definitive evidence for a metabolic disorder and to guide treatment.

• Confirming Homocystinuria: The most critical use is to confirm the diagnosis of Homocystinuria, an autosomal recessive disorder that leads to high levels of homocysteine excretion.
• Monitoring Treatment: Used frequently to monitor the effectiveness of treatment protocols for Homocystinuria, which may include high-dose Vitamin B6, B12, folate supplementation, or a low-methionine diet. Successful treatment should result in decreased homocysteine excretion.
• Assessing Metabolic Status: Provides a quantitative measure of the body’s metabolic status regarding methionine and related pathways, often correlating better with severe disease than plasma levels alone.
• Differential Diagnosis: Helps differentiate between nutritional hyperhomocysteinemia (often mild and responsive to B-vitamins) and genetic hyperhomocysteinemia (Homocystinuria, which may be severe and life-long).

Who Should Get the Homocysteine – Urine Test Done?

This test is typically ordered by a paediatrician, Metabolic Specialist, or Geneticist when clinical or laboratory evidence strongly suggests a severe metabolic disorder.

You may be advised to take this test if:

• You are an infant or child with unexplained symptoms such as developmental delay, dislocated lenses (ectopia lentis), skeletal abnormalities, or recurrent blood clots.
• You have had persistently and significantly elevated plasma homocysteine levels that are not fully explained by common vitamin deficiencies.
• You have a known family history of Homocystinuria and require screening or carrier testing.
• You are a patient currently undergoing treatment for Homocystinuria, and your physician needs to monitor the therapeutic response.

Components of Homocysteine – Urine

The test measures the total concentration of homocysteine and its derivatives in the collected urine sample.

Understanding a Homocysteine – Urine Report

The report provides a quantitative value, typically expressed as a concentration (in micromol/L), a ratio to creatinine, or as an absolute excretion rate (micromol/24 hours). A typical normal range for the 24-hour collection is usually less than 10 micromol per 24 hours, though this can vary. The result must always be interpreted by a specialist in the context of the patient's symptoms, clinical history, and other diagnostic tests. The reporting formats and the exact reference range may vary slightly between laboratories, depending on their analytical methods and regional guidelines.

Interpretation Note: The most significant finding is severe elevation, which, when combined with a specific clinical picture, is diagnostic for Homocystinuria. For monitoring treatment, the goal is typically to achieve a reduced or normal level of homocysteine excretion, indicating effective metabolic control.

Preparation and Procedure for the Homocysteine – Urine Test

The key consideration for this test is the accurate collection of the urine specimen, especially if a 24-hour sample is requested.

How Homocysteine – Urine Test Performed?

The patient or caregiver is instructed on how to perform either a random or 24-hour urine collection. For the 24-hour test, all urine produced over a full 24-hour period must be collected in a specialised container provided by the lab, which often contains a preservative to stabilise the homocysteine. The collected sample is then transported back to the lab, where it is processed using mass spectrometry or a similar high-precision technique to measure the total concentration of homocysteine and its metabolites.

Is Fasting Needed Before the Test?

No, fasting is not required for the Homocysteine – Urine test.

Can Medications Affect the Test Results?

Yes. Certain medications or supplements can influence results. It is essential to inform your doctor about any recent or current high-dose vitamin supplementation (particularly B6, B12, or folate) or any drugs that affect homocysteine metabolism, as these can artificially lower the levels and complicate the diagnosis.

What Is the Best Time of Day to Take the Test?

If a random urine sample is requested, the time of day is less critical. If a 24-hour collection is requested, the collection must start and end at precise times (e.g., 8:00 AM on day 1 to 8:00 AM on day 2) to ensure the entire day's output is captured accurately.

How Frequently Is the Test Needed?

This test is typically performed once for diagnosis. However, for patients who have been diagnosed with Homocystinuria, the test may be repeated frequently (monthly to quarterly) to monitor the effectiveness of dietary and vitamin therapies.
