Thyroid Function Ordering Algorithm

← Back to document page

Thyroid Function Ordering Algorithm Nonhospitalized patients without known or suspected pituitary disease Begin evaluation by Ordering either the cascade approach THSCM / Thyroid Function Cascade, Serum (all appropriate tests are performed automatically). or order each test individually, beginning with STSH / Thyroid -Stimulating Hormone-Sensitive (s-TSH), Serum s-TSH. Functional sensitivity: mIU/L. < mIU/L* mIU/L* mIU/L* > mIU/L*. Hyperthyroid suspect Borderline low TSH No further testing Hypothyroid suspect unless clinically indicated Order Free T4: Order Free T4: Order Free T4 and TP0: FRT4 / T4 (Thyroxine), FRT4 / T4 (Thyroxine), FRT4 / T4 (Thyroxine), Free, Serum Free, Serum Free, Serum TPO / Thyroperoxidase (TPO).
