A friend called last weekend requesting me to give him some clues about the “TNTC” written on his urinalysis report. Well, for those of you who are not aware of its definition, TNTC is an acronym for too numerous to count.
In urinalysis, we, laboratory technicians or better known as medical technologists, count the number of cellular elements, such as WBC, RBC, we find under a microscope. If the fields, however, are packed with cellular elements, we report it as TNTC or too numerous to count. We do this because it would be impractical to count their real numbers.
