Quizplus · Accepted Answer

The copper sulfate method is a CLIA-waived, manual method of determining the hemoglobin level.It is often used to screen blood donors.The test is based on the principle of specific gravity; when a drop of blood from a patient with a normal hemoglobin value is dropped into a copper sulfate solution, it falls rapidly to the bottom.If the drop falls slowly or not at all, the hemoglobin level is below reference range.
