Are there variances of calculated free testosterone attributed to variations in albumin and sex hormone-binding globulin concentrations in men?

Objective: Calculated free testosterone (cFT) is determined from total testosterone (TT), sex hormone binding globulin (SHBG), and albumin (Alb) levels using mathematical formulae. Variations in cFT due to changes in SHBG or Alb have not been investigated. We evaluated potential cFT variances determined with fixed Alb (4.

Dengue fever mimicking plasma cell leukemia.

Extreme plasmacytosis in peripheral blood is a rare finding most often associated with plasma cell leukemia but rarely with other malignancies, infectious diseases, or drug reactions. We report the case of a 40-year-old man who was a US expatriate working and traveling in East Asia.
