Abstract
A novel method and reagent useful therein are cyanide-free and capable of providing a rapid indication, e.g., less than 30 seconds, of total hemoglobin in a blood sample, so as to find particular application in automated hematological instrumentation. The novel reagent comprises an ionic surfactant, a pH of at least about 11.3 and is free of ionic cyanide. The ionic surfactant itself can impart the required pH or a strong base independent of such surfactant may be included.
