The serum PB127I, T3 resin uptake, and thyroxine (T4) concentration were measured and the free thyroxine and free Thyopac indices calculated in 97 people aged 70 or more living at home. PB127I was below 4 µg/100 ml in eight subjects, of whom four were shown by the other tests to be hypothyroid. A drug history indicated the likely cause of a PB127I of over 8.5 µg/100 ml in three of nine subjects, all of whom were shown to have normal thyroid function by the other tests. No relation was demonstrable between PB127I and serum albumin concentration.
The value of these tests as part of a screening programme for the elderly is discussed.
