Thyroid and prolactin round out the picture. Sudden severe acne with rapid hair growth or a deepening voice needs prompt evaluation. ## When should you see a clinician instead of ordering a test? - Rapid-onset severe acne with a deepening voice, enlarged clitoris or sudden facial hair growth — prompt evaluation for an androgen-producing tumor - Acne with fever, painful deep nodules and feeling unwell (possible acne fulminans) - Periods that have stopped for three months or more without pregnancy ## Why these tests for adult acne? Androgens drive oil production. Total and free testosterone with SHBG show how much active hormone is reaching the skin; DHEA-S separates an adrenal source from an ovarian one. In women, LH, FSH and AMH support or exclude PCOS, the most common hormonal cause. Insulin resistance lowers SHBG and pushes the ovaries to make more testosterone, so fasting insulin and A1c are part of the same evaluation and change what treatment makes sense. TSH and prolactin are checked because thyroid disorders and high prolactin disturb cycles and skin, and are easily treated when found. ## Which conditions do these tests help evaluate? - [PCOS](https://www.test-well.com/conditions/pcos) — Androgens, LH/FSH, insulin and thyroid markers to investigate PCOS. - [Thyroid Problems](https://www.test-well.com/conditions/thyroid-problems) — TSH, Free T4/T3 and antibodies to evaluate an under- or over-active thyroid. ## Which tests, and what do they cost? | Test or panel | Type | Price | All-in (one item + $6 fee) | Fasting | Results | | --- | --- | --- | --- | --- | --- | | [Women's Hormone Panel](https://www.test-well.com/tests/womens-hormone-panel) | Panel (11 tests) | $239.99 | $245.99 | No | 3–5 business days | | [Women's Hair Health Panel](https://www.test-well.com/tests/womens-hair-health-panel) | Panel (19 tests) | $469.99 | $475.99 | No | 4–7 business days | | [Pre-Diabetes Panel](https://www.test-well.com/tests/pre-diabetes-panel) | Panel (5 tests) | $89.99 | $95.99 | Yes | 2–5 business days | | [Testosterone, Free & Total + SHBG](https://www.test-well.com/tests/testosterone-free-total-shbg) | Test | $69.99 | $75.99 | No | 3–5 business days | | [DHEA-Sulfate](https://www.test-well.com/tests/dhea-sulfate) | Test | $32.99 | $38.99 | No | 1–3 business days | | [LH (Luteinizing Hormone)](https://www.test-well.com/tests/luteinizing-hormone) | Test | $36.99 | $42.99 | No | 1–3 business days | | [FSH (Follicle Stimulating Hormone)](https://www.test-well.com/tests/fsh) | Test | $29.99 | $35.99 | No | 2–4 business days | | [Egg Reserve & Fertility Test (AMH)](https://www.test-well.com/tests/amh) | Test | $74.99 | $80.99 | No | 3–5 business days | | [Insulin, Fasting](https://www.test-well.com/tests/insulin-fasting) | Test | $22.99 | $28.99 | Yes | 2–4 business days | | [Hemoglobin A1c](https://www.test-well.com/tests/hemoglobin-a1c) | Test | $21.99 | $27.99 | No | 2–4 business days | | [TSH (Thyroid Stimulating Hormone)](https://www.test-well.com/tests/tsh) | Test | $26.99 | $32.99 | No | 1–3 business days | | [Prolactin](https://www.test-well.com/tests/prolactin) | Test | $39.99 | $45.99 | No | 2–4 business days | | [Estradiol (E2)](https://www.test-well.com/tests/estradiol) | Test | $35.99 | $41.99 | No | 1–3 business days | Prices are cash-pay; every order adds one $6.00 lab processing fee.

Morning, ideally days 2–5 of the cycle for LH/FSH/estradiol, and off hormonal birth control for several weeks if you want an unmasked androgen picture — the pill raises SHBG and lowers free testosterone. ### Can acne be the only sign of PCOS? It can be the most visible one. PCOS is diagnosed from two of three: irregular ovulation, high androgens (lab or clinical), and polycystic ovaries on ultrasound. Persistent adult acne plus irregular cycles is enough to test. ### Do men need hormone tests for acne? Rarely. Adult male acne is seldom due to abnormal hormone levels unless testosterone, DHEA or anabolic supplements are involved — in which case a testosterone and DHT check is informative. ## Related - [What blood tests should you get for fatigue?](https://www.test-well.com/symptoms/fatigue) - [Which blood tests help explain brain fog?](https://www.test-well.com/symptoms/brain-fog) - [What blood tests should you get for hair loss?](https://www.test-well.com/symptoms/hair-loss) - [What blood tests check for causes of unexplained weight gain?](https://www.test-well.com/symptoms/weight-gain) - [All symptoms](https://www.test-well.com/symptoms) - [Browse by condition](https://www.test-well.com/conditions) ## Sources - [American Academy of Dermatology — Adult acne](https://www.aad.org/public/diseases/acne/really-acne/adult-acne) - [Office on Women's Health — Polycystic ovary syndrome](https://www.womenshealth.gov/a-z-topics/polycystic-ovary-syndrome) --- Medically reviewed by Youmna DiStefano, MD (Medical Reviewer, TestWell); last reviewed 2026-09-06.
