Test Overview & Methodology
The Aspirin Resistance (11‑Dehydrothromboxane B2) Test is a specialized urine immunoassay that quantifies the stable metabolite of thromboxane A2, 11‑dehydrothromboxane B2, to assess the efficacy of aspirin antiplatelet therapy. It is indicated for patients on long‑term aspirin for cardiovascular protection.
This test helps determine if your current aspirin dose adequately suppresses platelet aggregation. Elevated levels in the urine may indicate incomplete inhibition due to absorption issues, non‑compliance, or true pharmacological resistance.
| Feature | Our Test | Closest Alternative |
|---|---|---|
| Precision / Diagnostic Sensitivity | 99.9% (ISO‑Validated Immunoassay) | Platelet Aggregometry (variable, operator‑dependent) |
| Methodology | Quantitative Immunoassay (ELISA) – highly specific for 11‑dhTXB2 | Light Transmission Aggregometry (LTA) – indirect platelet function |
| Turnaround Speed | 2–3 weeks (sample must be collected by the 7th of the month for batch processing) | Typically 1–2 weeks, but less stable urine markers |
Pre‑Test Instructions: Take aspirin exactly as prescribed. Avoid NSAIDs for 48 hours prior to collection. Collect morning urine after discarding the first void. A urine collection kit will be provided at your doorstep. Please complete and return the Test Send Out Consent Form (Form 35) with the sample.
Physician Insight & Safety Protocols
Dr. Ajay Singh (DHA: 36234132) notes: "This urine test provides a reliable long‑term view of aspirin's effect on thromboxane production. It is a valuable tool for patients who have not had prior cardiovascular events but are on aspirin prophylaxis. However, a single elevated result does not necessarily mean you should stop your medication. Always discuss findings with your prescribing physician before making any changes."
Important Medication Advisory
⚠️ Medication Warning
Do not discontinue prescribed aspirin without consulting your doctor. Unsupervised cessation may increase the risk of heart attack or stroke. This test is a monitoring tool, not a directive to stop therapy.
Exclusion Criteria & Emergency Red Flags
- Exclusion: Pregnancy, known aspirin hypersensitivity, active gastrointestinal bleeding, severe renal impairment (eGFR <30 mL/min), or haemophilia.
- Red Flags – Seek immediate emergency care if you experience: sudden chest pressure, shortness of breath, facial drooping, arm weakness, slurred speech, or severe headache with visual changes.
Patient FAQ & Clinical Guidance
1. What is the Aspirin Resistance (11‑Dehydrothromboxane B2) Test?
This urine test measures the level of 11‑dehydrothromboxane B2, a stable metabolite of thromboxane A2, to evaluate how effectively aspirin is inhibiting platelet aggregation. Elevated levels while on a standard dose may indicate resistance.
2. Why is urine preferred over blood for this test?
Urinary 11‑dehydrothromboxane B2 provides a non‑invasive, integrated measure of systemic thromboxane production over several hours. It avoids ex vivo platelet activation during venipuncture, which can cause false elevations in serum thromboxane tests.
3. How should I prepare and what do the results mean?
Take aspirin exactly as prescribed, avoid NSAIDs for 48 hours, and collect a morning urine sample after discarding the first void. Normal ranges are assay‑specific; levels above 1500 pg/mg creatinine often suggest suboptimal aspirin effect. Always discuss your results with a physician.
