Clinical Significance
Precision in the estimation of TSH is crucial to the follow-up of subjects with thyroid disorders. The preincubation of samples to remove HAMA immunoglobulins provides a way to ensure that an otherwise unsuspected rise or drop in TSH concentration will not be interpreted as either a false positive or false negative.
