About the test

How does the home thyroid test work?

With this home test, you can easily measure your levels of free T3, free T4 and TSH (thyroid-stimulating hormone) using a small blood sample. Here’s how it works:

  • Finger-prick device
    Collect a blood sample at home using the included lancet device.
  • Send your sample
    Place the sample tube in the protective bag with the absorbent pad and send it to the laboratory using the prepaid return envelope.
  • Results
    You will usually receive your results one day after your sample has been received by the laboratory, via your personal online dashboard.

What insights does the test provide?

  • TSH (thyroid-stimulating hormone) regulates the production of thyroid hormones.
  • Free T4 and free T3 are the active thyroid hormones and play an important role in regulating your metabolism and energy use.

By looking at these three values, you can gain insight into whether your thyroid is functioning normally, too slowly (hypothyroidism) or too quickly (hyperthyroidism):

  • With hypothyroidism, TSH is often elevated while T3/T4 levels are lower.
  • With hyperthyroidism, TSH is typically lower while T3/T4 levels are elevated.

What can you do with your results?

Your results can show whether your thyroid levels are within the normal range or whether further testing by your doctor may be advisable. This gives you a quick insight into your thyroid health, without having to leave home. Test results provide a snapshot in time and can be influenced by factors such as diet, lifestyle, medication and the time of sample collection. Abnormal results do not automatically mean that you have a medical condition.

Symptoms of hypothyroidism

Symptoms of thyroid disorders

The thyroid plays an important role in regulating your metabolism and energy levels. If your thyroid is underactive or overactive, it can cause a range of symptoms. Below you can find symptoms that may indicate an underactive (hypo-) or overactive (hyper-) thyroid.

Recognise the symptoms of an underactive thyroid (hypothyroidism)

When your thyroid does not produce enough hormones, your metabolism slows down. This can cause symptoms such as:

  • Persistent fatigue
  • Weight gain
  • Sensitivity to cold
  • Muscle and joint pain
  • Dry skin
  • Thinning hair
  • Slow heart rate
  • Constipation
  • Low mood or depressive feelings
  • Puffy face
  • Enlarged thyroid gland (goitre)
  • Heavy or irregular periods

Recognise the symptoms of an overactive thyroid (hyperthyroidism)

With an overactive thyroid, your body produces too much thyroid hormone, causing your metabolism to speed up. This can lead to:

  • Unexplained weight loss
  • Heart palpitations or an irregular heartbeat
  • Difficulty sleeping
  • Nervousness, anxiety or irritability
  • Excessive sweating
  • Trembling hands
  • Sensitivity to heat
  • Enlarged thyroid gland (goitre)
  • Increased appetite
  • Changes in menstrual cycle
  • Fatigue despite an increased metabolic rate
Biomarker summary

TSH – The link between the brain and thyroid

TSH stands for thyroid-stimulating hormone and is produced by the pituitary gland, a small gland in the brain. TSH signals the thyroid to produce the hormones T3 and T4. A high or low TSH level may indicate an underactive thyroid (hypothyroidism) or an overactive thyroid (hyperthyroidism). TSH is therefore an important indicator when assessing thyroid function.

FT3 – The active thyroid hormone

FT3 stands for free triiodothyronine and is the biologically active form of T3, the hormone that directly influences your metabolism. Although most T3 in your blood is bound to proteins, only free (unbound) FT3 is available for use by your body’s cells. FT3 plays a role in:

  • Burning calories
  • Regulating body temperature
  • Heart rate and digestion
  • Brain function and muscle coordination

Some FT3 is produced in the tissues by converting FT4 into FT3.

FT4 – The main circulating thyroid hormone

FT4 stands for free thyroxine and is the free form of T4, another important hormone produced by the thyroid. FT4 production is regulated by the hypothalamus and pituitary gland and is essential for:

  • Energy metabolism
  • Proper organ function
  • A healthy metabolism

Abnormal FT4 levels can be associated with symptoms such as fatigue, weight changes, mood changes or heart problems. Measuring FT4 together with TSH and FT3 can therefore provide useful insight when assessing thyroid function.

Frequently Asked Questions Everything about Thyroid test

Thyroid tumours are abnormal collections of cells in or on the thyroid gland. In most cases, these growths are benign and do not cause any symptoms.

However, some growths can:

  • Be malignant (cancerous)
  • Become visible or noticeable as they grow larger
  • Produce too much thyroid hormone (T4), which can lead to hyperthyroidism

Symptoms of this may include weight loss, palpitations, and nervousness.

A blood test can help detect a hormone imbalance, but a complete assessment requires medical examination by a doctor, such as an ultrasound or a biopsy.

The home test from Labtest.nl is just as reliable as a blood test performed by your doctor, hospital, or laboratory. All tests are scientifically validated and analysed in an ISO-accredited laboratory that also works with healthcare professionals. You receive a test kit containing all necessary materials and a clear step-by-step guide. This allows you to safely and correctly collect a blood sample through a simple finger prick, right at home, at a time that suits you. In short: medical quality, without the hassle of an appointment.

Yes, both thyroid conditions can be treated effectively, although the approaches are different.

Treatment of hyperthyroidism (overactive thyroid):

  • Thyroid-blocking medication to reduce the production of hormones
  • Radioactive iodine, which partially destroys the thyroid gland to prevent excessive hormone production
  • In some cases: surgery to remove part or all of the thyroid gland

After removal, lifelong use of synthetic thyroid hormones is often needed to maintain hormone balance.

Treatment of hypothyroidism (underactive thyroid):

  • Daily intake of synthetic thyroid hormone (usually levothyroxine)
  • This helps restore hormone levels to normal and reduce symptoms

With the right treatment, most people can lead a normal and healthy life.

Hyperthyreoïdie ontstaat wanneer je schildklier te veel schildklierhormonen (T3 en T4) aanmaakt. Dit versnelt je stofwisseling en kan leiden tot klachten zoals Hyperthyroidism occurs when the thyroid gland produces too much thyroid hormone (T3 and T4). This speeds up your metabolism and can lead to symptoms such as palpitations, weight loss, trembling, or nervousness.

  • Possible causes include:
  • Autoimmune disorders, such as:
    • Graves’ disease (the most common cause)
    • Plummer’s disease (toxic multinodular goitre)
    • Thyroiditis (inflammation of the thyroid gland), for example after pregnancy or a viral infection
    • Overactive thyroid nodules (benign lumps that produce too much hormone)
    • Excessive iodine intake, through food or supplements
    • A benign tumour of the pituitary gland, which stimulates the thyroid too strongly through TSH

A blood test measuring TSH, free T3, and free T4 is essential to diagnose hyperthyroidism.

With a home test, you can easily and reliably check whether your thyroid is functioning properly from the comfort of your own home.

The HealthPro Thyroid Check measures the 3 most important thyroid values:

  • TSH (thyroid-stimulating hormone)
  • Free T3

It is ideal if you have symptoms such as fatigue, weight fluctuations, or mood changes and want to quickly understand what may be going on.

Although anyone can develop thyroid problems, you have a higher risk if you:

  • Are a woman (women are 8 to 10 times more likely to develop thyroid problems than men)
  • Are older than 50 years
  • Have recently been pregnant (within the past 6 months)
  • Have a family history of thyroid disorders
  • Have an autoimmune disease, such as type 1 diabetes or Hashimoto’s disease
  • Smoke
  • Have previously had radiation treatment around the neck area
  • Have previously been treated with radioactive iodine or medication for thyroid disorders
