A drop of blood, allowed to fall into a copper sulfate solution of specific gravity 1.053, becomes encased in a sac of copper proteinate, which prevents dispersion of fluid for 15 seconds. If the specific gravity of blood is higher than the solution, the drop will sink or else it will remain suspended for some time.
Edit to clarify: In my years of blood donation the test for iron level was to put a drop of my blood in a solution of copper sulfate and time how long it took for the drop to fall to the bottom. As I got towards the end of my donation career I began to fail this test however a more accurate test would then be done and I would pass that test. A drop of b lood, allo wed to fall into a copper sulfate solution of specific gravity 1.053, becomes encased in a sac of copper proteinate, which prevents dispersion of fluid for
The copper sulphate (CuSO4) method is mostly used to ensure a certain Hb level for blood donation. A blood droplet is allowed to fall into copper sulphate solution of a specific gravity, equivalent to that of blood with the cut-off hemoglobin level, e.g. 12.5 g/dL (125 g/L). If the drop of blood floats or takes too long to sink, the donor is .
An excess of copper (II) sulfate solution (to make sure that all the iron is reacted) will be added to a known amount of iron. The metallic copper produced will be weighed. These weighings will be used to calculate the moles of iron used and the moles of copper formed. If equation (1) is correct, the moles of copper should equal the moles of iron.
