Which of the following most closely represents the lowest detection limit for third generation TSH Assays-
The current standard of care calls for the use of the third generation TSH assays with functional sensitivity of <0.02 mIU/L , a level of sensitivity necessary for detecting degrees of TSH suppression. The current third generation chemiluminescent immunoassays provide excellent sensitivity and specificity as well as the necessary low limits of detection and quantification. Ref - semantischolar.org
