Mass screening for complete deficiency of thyroxine-binding globulin in adult Japanese by comprehensive health examination.

Thyroxine-binding globulin capacity and concentration evaluated from blood spots on filter-paper in a screening program for neonatal hypothyroidism.

We describe a simple method for evaluating thyroxine-binding globulin capacity and concentration from a single 1-cm blood spot on filter-paper used in a screening program for neonatal hypothyroidism. This method permits prompt diagnosis of about 90% of the infants with thyroxine-binding globulin deficiency in our abnormal low-thyroxine, low-thyrotropin population. There was excellent equivalenc...

Familial thyroxine-binding globulin deficiency.

Genetically determined thyroxine-binding globulin deficiency is described in two families in the United Kingdom. All subjects in both pedigrees were euthyroid. Transmission was by sex-linkage; males showed low serum protein bound iodine and high thyroxine (T4) resin uptake due to complete absence of serum thryroxine-binding globulin; females were less severely affected. The distinctive biochemi...

The Evaluation of Serum Level of Testosterone and Sex Hormone- Binding Globulin in Men with Type 2 Diabetes

OBJECTIVE: To evaluate the relationship between serum level of testosterone and sex hormone-binding globulin in men with type 2 diabetes. MATERIALS AND METHODS: In this case-control study, forty men aged 40-70 with type 2 diabetes mellitus were randomly selected and compared with 40 non-diabetic men. The two groups were matched for their age and BMI. After complete observation and examination...

Radioelectrophoresis for determination of thyroid hormone binding abnormalities in human serum.

This paper describes a rapid and accurate method for determining binding abilities of thyroid hormones to their corresponding serum proteins: prealbumin, albumin and thyroxine binding globulin. A tube cell agarose gel electrophoresis is used with radioactive labelled triiodothyronine or thyroxine. The distribution curve shows characteristic peaks for prealbumin, albumin and thyroxine binding gl...
