Test Overview & Methodology
The Dihydrotestosterone (DHT) Free Test precisely quantifies the unbound, biologically active fraction of DHT using equilibrium dialysis followed by liquid chromatography‑tandem mass spectrometry (LC‑MS/MS). This gold‑standard assay resolves diagnostic ambiguities in androgen excess disorders such as idiopathic hirsutism, polycystic ovary syndrome, androgenetic alopecia, and 5α‑reductase deficiency, surpassing the specificity limitations of conventional immunoassays. The method involves a 3 mL serum sample collected in a Red Top tube (no additive, no SST gel barrier), shipped refrigerated or frozen. Due to the complexity of equilibrium dialysis, samples are batch processed once per month; specimens must arrive by the 7th of the month for inclusion in the current batch.
| Feature | Our DHT Free Test (LC‑MS/MS + Equilibrium Dialysis) | Standard Immunoassay (Closest Alternative) |
|---|---|---|
| Analytical Specificity | 99.9% – no cross‑reactivity | Moderate – potential cross‑reactivity with other steroids |
| Free vs Total Distinction | True free DHT after dialysis | Calculated or indirect estimate |
| Turnaround Time | 2–3 weeks (batch processing by 7th of the month) | Typically 3–5 days |
| Price (AED) | 4500 | 500–1500 |
Physician Insight & Safety Protocols
“As a DHA‑licensed general practitioner, I emphasise that an isolated free DHT value must be correlated with total testosterone, SHBG, and clinical signs. A normal free DHT does not exclude subtle androgen excess; always interpret alongside symptoms such as hirsutism or acne. This test should guide, not replace, a comprehensive endocrine evaluation. Always review medication history including finasteride or dutasteride use before testing.” – Dr. Ajay Singh (DHA: 36234132)
⚠ Medication Warning
Do not discontinue prescribed medication without consulting your doctor. Finasteride, dutasteride, and certain hormonal therapies can significantly lower DHT measurements; inform your physician of all supplements and medications prior to blood draw.
Exclusion Criteria & Safety Red Flags
- Known hypersensitivity to phlebotomy; active skin infection at venipuncture site.
- Pregnancy (altered reference ranges; prioritise obstetric guidance).
- Severe liver dysfunction (affects hormone‑protein binding).
- Emergency red flags: sudden voice deepening, clitoromegaly, rapid virilisation – seek immediate endocrine emergency consultation.
Patient FAQ & Clinical Guidance
-
The dihydrotestosterone free test measures the unbound, biologically active form of DHT using equilibrium dialysis and LC‑MS/MS. It is essential for diagnosing androgen excess disorders such as idiopathic hirsutism, polycystic ovary syndrome, and 5α‑reductase deficiency when total DHT levels are inconclusive.
-
No fasting is required, but avoid biotin supplements for 48 hours prior. The red‑top tube without gel ensures no interference from separator gels, maintaining DHT stability during refrigerated transport to our ISO‑certified lab.
-
Due to specialised equilibrium dialysis and batch processing required for high accuracy, samples are processed monthly. Our VIP Mobile Phlebotomy service (daily 8 AM – 11 PM) uses cold‑chain logistics to safely transport your specimen, with report delivery via secure portal. Specimens must be received by the 7th of the month for inclusion in the current batch.
