Prepare for the Test

  • Wash your hands thoroughly with soap and warm water or use the alcohol wipe provided. Allow your hands to dry.

  • Open the test kit and lay out all components on a clean, flat surface.

  • Allow the test cassette and buffer liquid to reach room temperature (15-30°C) before starting.

​

Collect Your Blood Sample

  • Massage your fingertip (middle or ring finger) to increase blood flow.

  • Remove the protective cap from the lancet and position it on the side of your fingertip (avoid the center for comfort).

  • Press firmly until you hear a click. After the puncture, wipe away the first drop of blood with a tissue or gauze

​

Transfer the Blood Sample

  • Gently squeeze your fingertip to form a small blood drop.

  • Use the fine-tip dropper to collect blood to fill the thin part of the tube. Ensure to hold the pressure on the fine-tip dropper so that the blood drop remains within the thin part of the tube.

  • Hold the dropper vertically over the test cassette and release one drop into the sample well (marked "S").

​

Add the Buffer Solution & Start Timer

  • Add 2 drops of the buffer liquid into the sample well.

  • Start a timer and wait 15 minutes for the test to develop.

  • Do not read results after 30 minutes, as they may be inaccurate.

How to Interpret Your Results

TSH Results.png

✅ Negative (Normal TSH Levels)

  • Only the Control (C) line appears.

  • Your TSH level is below 5 μIU/mL.
     

âš  Positive (Elevated TSH Levels – Possible Hypothyroidism)​

  • Two lines appear – one in the C-line and one in the T-line.

  • This suggests TSH levels are above 5 μIU/mL, indicating possible hypothyroidism.

  • Consult a doctor for further evaluation.
     

🚫 Invalid Test Result

  • If no C-line appears, the test is invalid.

  • Retake the test using a new kit.

Important Notes 

âš  This test is a screening tool for hypothyroidism. If positive, further medical evaluation is required.

âš  Factors like pregnancy, medications, and iodine levels can influence TSH levels. Consult a doctor for a full thyroid assessment.

âš  Do not reuse any test components. Dispose of used items according to local regulations.

âš  The test detects TSH levels above 5 μIU/mL, which may indicate an underactive thyroid (hypothyroidism).

FAQ's

1. What does this test measure?
The test detects Thyroid-Stimulating Hormone (TSH) levels in blood. High TSH suggests the thyroid is not producing enough hormones (hypothyroidism).

2. How accurate is the test?
The TSH Rapid Test has 95.56% sensitivity and 99.25% specificity, making it a highly reliable screening tool.

3. What should I do if my test is positive?
A positive result means TSH levels maybe high, suggesting possible hypothyroidism. You may wish to consult a doctor for further blood tests and treatment options.

4. Can this test detect hyperthyroidism (overactive thyroid)?
No. This test is only designed to detect high TSH, which indicates hypothyroidism. Hyperthyroidism requires a different type of test.

5. What should I do if my test is invalid?
Repeat the test with a new kit. Ensure correct sample collection and follow instructions carefully.
