I'm not familiar with the phrase Superchem. It may be a panel name for a particular laboratory, like Antech. We use IDEXX at my hospital and their chemistry panels do not have thyroid values. We have to request separate panels of thyroid. A CBC is the count and percentage of cells in blood (red blood cells, the various white blood cells, platelets etc). Long as there is serum left after the chemistry, thyroid can certainly be added on. The independent labs can make a little serum go a long way. We can run chemistries in house, but we send out for thyroid because we don't keep those reagents on hand.
