Tsh ultrasensitive high

Screening for thyroid dysfunction and detecting mild (subclinical), as well as overt, primary hypo- or hyperthyroidism in ambulatory patients Monitoring patients on thyroid replacement therapy Confirmation of thyrotropin (TSH, formerly thyroid-stimulating hormone) suppression in thyroid cancer patients on thyroxine suppression therapy Prediction of thyrotropin-releasing hormone-stimulated TSH response High Sensitivity-Thyroid Stimulating Hormone HS-TSH (High Sensitivity Thyroid-Stimulating Hormone) S-TSH (Sensitive-Thyroid-Stimulating Hormone) Sensitive TSH (Thyroid-Stimulating Hormone) Thyroid-Stimulating Hormone-Sensitive (S-TSH), Serum Thyrotropin TSH (Thyroid-Stimulating Hormone)-High Sensitivity TSH Hypersensitive TSH, 3rd Generation TSH-ICMA Ultra-Sensitive TSH (Thyroid Stimulating Hormone) This is a standalone test for sensitive thyrotropin (s-TSH; formerly thyroid-stimulating hormone). If a cascade approach is preferred, order THSCM / Thyroid Function Cascade, Serum, which utilizes a cascaded testing procedure to efficiently evaluate and monitor functional thyroid status. Serum s-TSH is the first-line test and when the s-TSH result is abnormal, appropriate follow-up tests will automatically be performed. Collection Container/Tube: Preferred: Serum gel Acceptable: Red top Submission Container/Tube: Plastic vial Specimen Volume : 0.6 mL Collection Instructions: 1. Serum gel tubes should be centrifuged within 2 hours of collection. 2. Red-top tubes should be centrifug...
