Cardiac Enzymes and Hypothyroidism

using samples from 53 patients (mean age 66 y, range 37 to 88 y) with clinically and histologically confirmed cobrectal carcinoma and 12 patients (mean age 55 y, range 29 to 73 y) with other forms of cancer (nine gastric, two breast, and one ovarian). The in-house method was a double-antibody technique based upon a previously described method (2). We used only patients’ sera with increased in-house CEA values >30 g/L (in-house reference interval: <15 pg/L). The CEA values determined by the in-house method are different from usually quoted figures, because these figures were assigned before an international reference standard became available. Increased CEA values can also be seen in smokers, and in patients with liver diseases, ulcerative colitis, and several other disorders. However, CEA values exceeding five times the upper limit of normal are usually only seen in cancers of the gastrointestinal tract. For the in-house assay this would be >75 ,u.g/L, and for the Abbott assay (reference interval: <3 ug/L), >15 g/L. The aims of this comparison were (a) to establish whether more or fewer patients would be in the “grey area” of diagnosis and (b) to monitor and estimate any difference in the percentage increases in CEA, depending on the method used. 21 subjects. Since this amount of time was based on peak capillary BAC, actual absorption time would be somewhat longer than 100 mm. None of these 20-mm corrections require changes in either the discussion or the conclusions found in my article.
