Bloom Thyroid Test 

The Bloom Thyroid Test shows the thyroid status within minutes and can indicate primary hypothyroidism, an underactive thyroid. With a drop of blood it measures the thyroid-stimulating hormone (TSH) and creates a personalized analysis of the results on the Bloom App. Find out more about your TSH level with the Bloom Thyroid Test.

What is TSH?

TSH ("Thyroid Stimulating Hormone”) controls how the body uses and stores energy through the thyroid gland. Growth and development are also influenced by TSH. It is released by the pituitary gland, a small, bean-shaped organ located at the base of the brain. It then stimulates the thyroid gland to produce the thyroid hormones T4 and T3, which play an important role in regulating a variety of metabolic processes in the body.

Why measure TSH?

The pituitary and thyroid glands communicate closely to regulate hormone levels through a feedback mechanism. When the thyroid gland is not working properly or not producing enough hormones, the pituitary gland releases more TSH to stimulate the thyroid gland to produce more of these hormones. Because of this, high TSH levels are associated with hypothyroidism and therefore low T4 and T3 levels.  This condition is called hypothyroidism, or underactive thyroid.

The feedback mechanism also works in reverse, i.e. low TSH levels are associated with an overactive thyroid gland and thus high T4 and T3 levels - which is also called hyperthyroidism or hyperthyroidism.  In this case, metabolism accelerates and symptoms such as hyperactivity or weight loss may occur.

When is a Bloom Thyroid Test useful?

The Bloom Thyroid Test is recommended if you are curious or concerned about your TSH level and want to screen for hypothyroidism. Hypothyroidism is a condition that affects about 4.5% of the general population.  It is often difficult to identify because of its non-specific symptoms, such as weight gain, dry skin, hair loss, constipation, fatigue, and cold intolerance. By measuring TSH levels with the Bloom Thyroid Test, you will gain insight into whether or not your thyroid is underactive. Especially in many affected women, hypothyroidism is often diagnosed late.


Limitations: This test cannot be used to screen for hyperthyroidism or secondary/tertiary hypothyroidism*. TSH level may be below the detection limit of the device and indicated with a "<" (normal reference range: 0.4-4.5 mIU/L).

 *Not suitable if you: are under 18 years of age, are pregnant or have given birth in the last 12 months, have or have had thyroid cancer or pituitary adenoma, are under the influence of alcohol or drugs, or are in an acute emergency or distress situation. If in doubt, always consult a physician.
