Ordering the Female Serum Profile | ZRT Labs
The Female Serum Profile from ZRT Labs measures a comprehensive set of hormones and thyroid markers to help identify imbalances that may affect energy, mood, menstrual cycles, and reproductive health. Interestingly, this test can also reveal early signs of insulin resistance, which is often missed in routine checkups.
Ordering this test provides specific benefits:
- Tracks estrogen, progesterone, and testosterone levels to pinpoint hormone imbalances.
- Assesses thyroid function with TSH, Free T3, Free T4, and thyroid antibodies for a complete thyroid health picture.
- Measures cortisol and DHEAS to evaluate stress response and adrenal function.
- Includes Sex Hormone Binding Globulin to help clarify hormone availability in the body.
- Offers a convenient at-home collection kit for serum samples, making testing accessible and private.
Who Should Consider Comprehensive Female Hormone and Thyroid Testing
People who have been feeling tired, experiencing mood changes, or noticing changes in their menstrual cycle may benefit from this test. For example, someone who has been struggling with unexplained weight gain, hair loss, and trouble sleeping might find answers by checking their hormone and thyroid levels.
Ordering this test may also be helpful in these situations:
- Experiencing hot flashes or night sweats during menopause.
- Dealing with irregular periods or symptoms of polycystic ovary syndrome (PCOS).
- Facing challenges with fertility or planning for pregnancy.
- Noticing skin changes, such as dryness or acne, that do not improve with regular care.
- Having a family history of autoimmune thyroid conditions, which can sometimes show up as mood swings or anxiety before other symptoms appear.
Checking these markers can help identify hormone or thyroid issues that may be causing symptoms like fatigue, mood swings, or changes in body weight. Delaying this test could mean missing the chance to address hormone or thyroid imbalances early, which may lead to more persistent symptoms over time. To get a clearer picture of your hormone and thyroid status, consider ordering this test.

Low levels mean adrenal insufficiency or aging. |
| Sex Hormone Binding Globulin | 18-144 | Sex Hormone Binding Globulin (SHBG) controls how much testosterone and estrogen are available for the body to use. It helps balance hormone effects. |
High levels mean less free testosterone and estrogen, possibly from liver issues or high estrogen.
Low levels mean more free hormones, possibly from obesity or insulin resistance. |
