A Hirsutism profile blood test is designed to evaluate the underlying causes of hirsutism, which is the excessive growth of coarse, dark hair in areas where women typically have minimal or no hair (e.g., face, chest, back). Hirsutism is often related to an overproduction of androgens (male hormones) or a sensitivity to them. It can be caused by various conditions, including polycystic ovary syndrome (PCOS), adrenal gland disorders, or other hormonal imbalances.

The blood tests in a hirsutism profile typically focus on measuring hormone levels that regulate hair growth, reproductive function, and metabolism. These tests help identify any abnormalities that might be contributing to the excessive hair growth.

Common Tests Included in a Hirsutism Profile:

1. Testosterone (Total and Free)

  • Purpose: Measures the levels of total testosterone (all testosterone in the blood) and free testosterone (testosterone that’s not bound to proteins and is biologically active).
  • Why It’s Tested: Elevated testosterone levels are a common cause of hirsutism and are often seen in conditions like PCOS, congenital adrenal hyperplasia, or androgen-secreting tumors.

2. DHEA-S (Dehydroepiandrosterone Sulfate)

  • Purpose: Measures the levels of DHEA-S, an androgen produced by the adrenal glands.
  • Why It’s Tested: High levels of DHEA-S may indicate an adrenal gland disorder, such as adrenal hyperplasia or a tumor. Elevated DHEA-S is also associated with hirsutism.

3. Androstenedione

  • Purpose: Measures the levels of androstenedione, an intermediate androgen that can be converted into testosterone or estrogen.
  • Why It’s Tested: Elevated androstenedione levels are associated with PCOS, adrenal disorders, and some ovarian tumors. It’s another marker that helps assess androgen excess.

4. LH (Luteinizing Hormone) and FSH (Follicle-Stimulating Hormone)

  • Purpose: These hormones regulate the menstrual cycle and ovulation.
  • Why It’s Tested: An imbalance in the LH to FSH ratio (typically a higher LH level) is a hallmark of PCOS, a common cause of hirsutism. Testing these hormones helps in diagnosing PCOS and assessing reproductive function.

5. 17-Hydroxyprogesterone

  • Purpose: Measures a precursor hormone involved in the production of cortisol and androgens.
  • Why It’s Tested: Elevated levels of 17-hydroxyprogesterone suggest congenital adrenal hyperplasia (CAH), a genetic condition that can lead to excess androgen production and hirsutism.

6. Prolactin

  • Purpose: Measures the level of prolactin, a hormone produced by the pituitary gland.
  • Why It’s Tested: Elevated prolactin levels may indicate a pituitary disorder, which can disrupt hormone balance and contribute to hirsutism and irregular periods.

7. Cortisol

  • Purpose: Assesses the function of the adrenal glands.
  • Why It’s Tested: High cortisol levels may indicate Cushing’s syndrome, a condition where the body produces too much cortisol. This can cause hirsutism, weight gain, and other metabolic issues.

8. Sex Hormone-Binding Globulin (SHBG)

  • Purpose: Measures the protein that binds to sex hormones like testosterone, rendering them inactive.
  • Why It’s Tested: Low levels of SHBG mean more free testosterone is available in the blood, which can contribute to hirsutism. Reduced SHBG is commonly seen in conditions like PCOS.

9. Estrogen (Estradiol)

  • Purpose: Measures estrogen levels in the body.
  • Why It’s Tested: Low estrogen levels or imbalances between estrogen and androgens can contribute to menstrual irregularities and symptoms of hirsutism. Testing estradiol can help assess ovarian function and hormone balance.

10. Insulin and Glucose

  • Purpose: Measures blood sugar and insulin levels.
  • Why It’s Tested: Insulin resistance, often seen in PCOS, can lead to increased androgen production, which in turn contributes to hirsutism. Testing insulin and glucose levels helps in assessing the metabolic aspects of hirsutism.

11. Thyroid Function Tests (TSH, T4)

  • Purpose: Measures thyroid hormones to assess thyroid function.
  • Why It’s Tested: Thyroid dysfunction can cause hormonal imbalances that contribute to symptoms like hirsutism, along with other symptoms such as irregular periods or weight changes.

Conditions That May Cause Hirsutism:

  • Polycystic Ovary Syndrome (PCOS): The most common cause of hirsutism. Characterized by hormonal imbalances, including elevated androgens, irregular periods, and often insulin resistance.
  • Congenital Adrenal Hyperplasia (CAH): A genetic condition that leads to excessive androgen production.
  • Cushing’s Syndrome: Excess cortisol production that can cause hirsutism, weight gain, and high blood pressure.
  • Androgen-Secreting Tumors: Rare, but can be found in the adrenal glands or ovaries.
  • Hyperprolactinemia: Elevated prolactin levels can cause irregular periods and sometimes hirsutism.

Importance of the Hirsutism Profile:

This profile helps in determining the root cause of excessive hair growth and guides the treatment plan. Identifying the underlying condition can lead to effective management, which may include lifestyle changes, medications to reduce androgen levels, or treatments targeting the specific disorder (e.g., PCOS or adrenal issues).
