Check three key thyroid markers with an at-home test. The test measures TSH, free T3, and free T4, providing a comprehensive overview of pituitary signaling and thyroid hormone levels.
Test overview
- Sample collection entirely at home
- Liquid capillary blood from the fingertip
- 3 measured or calculated values
- Medical laboratory accredited to ISO 15189
- Quality assurance according to Rili-BÄK
- Digital results in a personal health portal
What does the test measure?
TSH
TSH is produced in the pituitary gland and regulates the thyroid's production of T4 and T3.
fT3
Free T3 is the unbound fraction of triiodothyronine, an active thyroid hormone.
fT4
Free T4 is the unbound fraction of thyroxine and serves, among other things, as a precursor to T3.
Common symptoms and when the test may be relevant
This combination can provide more information than TSH alone and may be relevant when experiencing symptoms associated with altered thyroid function or during follow-up.
Thyroid-related changes may occur alongside symptoms such as fatigue, feeling cold or hot, weight changes, heart palpitations, dry skin, constipation, or mood changes.
The symptoms are non-specific and can have many other causes. A laboratory test alone does not provide a diagnosis.
Who is this test for?
- For those who want to check TSH, fT3, and fT4 levels together.
- For those experiencing symptoms and seeking information for further assessment.
- For those who want to monitor previous thyroid levels.
How the at-home lab test works
- Order the test and receive the sampling kit at home.
- Read the instructions and prepare for the sample collection.
- Prick your fingertip and collect liquid capillary blood in the test tube.
- Label, pack, and send the sample to the laboratory.
- The laboratory analyzes the markers.
- View the results digitally in your personal health portal.
Before sample collection
For follow-up tests, it is recommended to collect the sample at approximately the same time of day, as TSH levels vary throughout the day. Follow the instructions and do not alter your thyroid medication without medical advice.
Laboratory and quality
The sample is analyzed at a medical laboratory accredited according to ISO 15189. The laboratory's quality assurance also adheres to the Rili-BÄK guidelines for laboratory medical testing.
- Sample material: liquid capillary blood
- Sampling location: at home
- Result: digital laboratory report
- Turnaround time: transport time and the scope of the analysis affect the total time
Results and reference values
The result displays the measured markers and any calculated values, along with the laboratory's units and current reference ranges. Results should be evaluated in conjunction with symptoms, medical history, and other relevant examinations.

Important information regarding the result
Contact a healthcare provider in the event of clearly abnormal results, persistent symptoms, or concerns. Seek medical attention promptly if you experience severe or rapidly worsening symptoms.
Frequently asked questions
What is TSH?
TSH is the signal sent by the pituitary gland to the thyroid gland.
What are fT3 and fT4?
They are the free, unbound fractions of the thyroid hormones T3 and T4.
Why should follow-up tests be taken at a similar time?
TSH levels vary throughout the day, and comparisons are more meaningful under similar conditions.
Can symptoms diagnose thyroid problems?
No. Symptoms are non-specific and must be evaluated alongside test results and medical information.
Can medications affect the results?
Yes. Never alter your prescribed thyroid treatment on your own.
