Total testosterone is the primary male hormone, essential for muscle development, bone strength, energy, and reproductive health. For men, monitoring testosterone levels may help identify changes that affect vitality and overall well-being.

Choose male or female — this range differs by sex.
Enter your age — this range changes with age.
This range also depends on context such as cycle phase or sample material; the highlighted rows apply to your group.

Bijsluiterwaarde: 5e-95e percentiel per subgroep (n = 136 mannen 20-49 jaar; 78 mannen 50 jaar en ouder; 89 vrouwen 20-49 jaar; 71 vrouwen 50 jaar en ouder), bij bloedafname tussen 06.30 en 13.00 uur en zonder gebruik van anticonceptiva. Testosteron kent een dagritme; een ochtendafname is de norm. Een hormoonreferentiewaarde is assay-specifiek; deze waarden gelden voor de Roche Elecsys-methode. Belangrijk bij vrouwen: de kwantificeringsgrens van deze immunoassay is 0,416 nmol/l, en beide onderste vrouwelijke grenzen (0,290 en 0,101 nmol/l) liggen daaronder. De tussenliggende precisie bij vrouwelijke concentraties is 8,2 % variatiecoefficient (cobas e 411, bij 0,406 nmol/l) tot 14,5 % (cobas e 601/e 602, bij 0,323 nmol/l), tegenover 1,8-3,0 % bij mannelijke concentraties. LC-MS/MS is de referentiemethode voor testosteron bij vrouwen; de bijsluiter adviseert zelf om een onverwacht verhoogde vrouwelijke uitslag te bevestigen met een extractiemethode of een gevalideerde LC-MS/MS-methode.

Reference ranges may vary between laboratories. When you order a test, a BIG-registered doctor assesses your personal results in context. For treatment decisions, discuss your results with your GP.
Check your own valueThis test measures the total amount of testosterone in your blood, reported in nmol/l. It includes both testosterone bound to proteins like SHBG and albumin, and the small fraction of free, unbound testosterone available for immediate use.
Testosterone is central to men's health, potentially influencing energy, strength, mood, and libido. Levels may naturally decline with age. Understanding your testosterone levels could help you and your healthcare provider make proactive decisions about your health.
Testing may be considered when experiencing fatigue, mood changes, reduced libido, or changes in body composition. Some healthcare providers recommend morning testing, as testosterone levels tend to be highest in the early hours of the day.
Low testosterone may cause fatigue, decreased libido, and muscle loss. Consider lifestyle changes (sleep, exercise, weight loss) and consultation with an endocrinologist for possible testosterone replacement.
Elevated testosterone may indicate steroid use, adrenal tumors, or testicular tumors. Consult with an endocrinologist for evaluation.
Regular resistance training, adequate sleep, stress management, and a balanced diet with sufficient zinc and vitamin D may support healthy testosterone levels. Limiting alcohol consumption could also be beneficial. Consult your healthcare provider for personalized guidance.
