Gene carriers for both forms of hemophilia can be detected through DNA studies in conjunction with results from factor VIII assays.
However, due to variable secretion of hGH, as well as hGH production in response to stress, exercise, or other factors, random assays are not an adequate determination of hGH deficiency.
However, reliable biological assays for measurement of immune function remain slow and cumbersome (e.g. lymphocyte proliferation by uptake of tritiated thymidine ).

These burners, or modifications of them, have also been applied to muffle furnaces, which are convenient when only a few assays have to be made - the furnace being a mere clay shell and soon brought to a working temperature; but the fuel is too expensive to allow of their being used habitually or on a large scale.
These cells then display a Treg phenotype and function as determined by FACS, T cell proliferation assays, ELISA and intracellular cytokine staining.
