TSH Ultrasensitive Serum

• Test Name: TSH Ultrasensitive Serum Test
• Test Type: Hormone assay
• Specimen Required: Blood sample (serum)
• Methodology: Immunoassay (typically chemiluminescent or electrochemiluminescent immunoassay)
• Purpose: Measures the concentration of thyroid-stimulating hormone (TSH) in the blood to assess thyroid function.

• Diagnosis: Helps diagnose thyroid disorders such as hypothyroidism and hyperthyroidism.
• Screening: Used for routine screening of thyroid function, especially in individuals at risk for thyroid disease.
• Monitoring: Monitors the effectiveness of thyroid treatment in patients with known thyroid conditions.
• Evaluation: Assesses thyroid function in individuals with symptoms of thyroid imbalance.

• Components:
  • Test kit with necessary reagents.
  • Instructions for sample collection and handling.
  • Calibration standards and quality control materials.
• Procedure:
  • Collection of a blood sample from the patient.
  • Processing of the sample to obtain serum.
  • Analysis of the serum using an immunoassay to determine TSH concentration.

• Normal Range: 0.4-4.0 mIU/L – Indicates normal thyroid function.
• Elevated TSH: >4.0 mIU/L – May indicate hypothyroidism or subclinical hypothyroidism.
• Low TSH: <0.4 mIU/L – May indicate hyperthyroidism or subclinical hyperthyroidism.
• Clinical Correlation: Results should be interpreted alongside clinical symptoms and other thyroid function tests, such as free T4 and free T3.

• Quantitative: Provides a numerical value for the concentration of TSH.
• Units: Results are typically expressed in milli-international units per liter (mIU/L).
• Reference Range: Established normal ranges for clinical interpretation.
• Turnaround Time: Typically within 1-2 days, depending on the laboratory.

Q. What is the TSH Ultrasensitive Serum Test?
The TSH Ultrasensitive Serum Test measures the level of thyroid-stimulating hormone (TSH) in the blood to assess thyroid function
 

Q. Why is the TSH Ultrasensitive Serum Test ordered?
This test is ordered to diagnose thyroid disorders, monitor thyroid treatment, and screen for thyroid dysfunction
 

Q. How is the TSH Ultrasensitive Serum Test performed?
A blood sample is drawn from the patient, and the serum is analyzed using an immunoassay to measure the TSH concentration
 

Q. What do the results of the TSH Ultrasensitive Serum Test indicate?
Results indicate whether the TSH levels are normal (0.4-4.0 mIU/L), elevated (indicating hypothyroidism), or low (indicating hyperthyroidism)
 

Q. Do I need to prepare for the TSH Ultrasensitive Serum Test?
No special preparation is needed, but it’s advisable to inform your healthcare provider about any medications you are taking, as they may affect the results
 

Q. How long does it take to receive results from the TSH Ultrasensitive Serum Test?
