Also known as: dihydrotestosterone, dht, 5α-dihydrotestosterone, 5-alpha-dihydrotestosterone, dihidrotestosteron
Reference range: 30–85 ng/dL (Source: ABIM)
Standard unit: ng/dL
High values may indicate
High DHT levels may indicate 5-alpha reductase overactivity, androgen-producing tumors, polycystic ovary syndrome (PCOS) in women, or use of testosterone supplements, and can contribute to male pattern baldness and benign prostatic hyperplasia.
Low values may indicate
Low DHT levels may indicate 5-alpha reductase deficiency (a genetic condition), hypogonadism, or use of 5-alpha reductase inhibitors (finasteride, dutasteride).
Frequently asked questions
- What is a normal Dihydrotestosterone (DHT) level?
- A typical reference range for Dihydrotestosterone (DHT) is 30–85 ng/dL (source: ABIM). Reference ranges vary by laboratory, age, and sex, so always compare against the range on your own lab report.
- What units is Dihydrotestosterone (DHT) measured in?
- Dihydrotestosterone (DHT) is most commonly reported in ng/dL. Labs in different countries may use other units — you can convert between them with BloodId's blood test unit converter.
- Where do Dihydrotestosterone (DHT) reference ranges come from?
- BloodId uses ABIM standard reference ranges and educational information from MedlinePlus (see our methodology). Reference ranges still vary by lab, age, and sex, so always compare against your own report.
- Can I track Dihydrotestosterone (DHT) over time?
- Yes. Upload results from any lab and BloodId charts your Dihydrotestosterone (DHT) over time against its reference range, so you can see whether the trend is rising, falling, or stable.
