When performing a testosterone level measurement, dl and ml are different units of measurement, with 1 dl = 100 ml. Testosterone is an androgen, with normal values of 1.3 to 2.8 nmol/L in adult women and 14 to 25.4 nmol/L in adult men, and the normal ranges may vary slightly from instrument to instrument. Different hospitals use different units of measurement, and if other units are used, conversions need to be made, 1L = 10dl, 1dl = 100ml. Too much as well as too little testosterone is detrimental to the body. Abnormal testosterone in women is often seen in polycystic ovary syndrome, and in men, it is often seen in testicular disease. If abnormal testosterone results are found in a checkup, it is important to go to the hospital in time to get medical attention, to clarify the cause of the hormone abnormality under the guidance of the doctor, and to take a standardized approach to treatment.
