[Assay of protein and thyroid hormone concentrations in hemofiltrate (author's transl)]

To assess protein and thyroid hormone loss during hemofiltration estimation of protein and thyroid hormone concentrations in the hemofiltrate were carried out. The protein loss during one week amounted to 4-6 g. Weekly loss of T4 was about 1,5 microgram, that of T4 0,5 microgram. These quantities are negligible and of no clinical relevance. Therefore substitutions of protein loss by albumin or thyroid hormones do not seem to be required in patients undergoing hemofiltration.
