[Behavior of thyroglobulin after fine needle aspiration of the thyroid].

The authors report the behaviour of serum concentration of thyroglobulin (TG) after fine needle aspiration biopsy of the thyroid. Compared with the basal level, serum concentration of thyroglobulin increase of 70% three minutes and of 341% sixty minutes after this maneuver. The authors agree with those who believe an interval of 10-15 days between fine needle aspiration biopsy of the thyroid and determination of serum concentration of thyroglobulin is necessary.
