At-Home Weight Loss Test Kit
Hormone, thyroid, and vitamin D context for weight-related symptoms and body-composition goals.
Consider this test if:
- Weight change is occurring alongside fatigue, sleep disruption, menstrual changes, or low libido
- Establishing hormone, thyroid, and vitamin D baselines before a structured weight-management program
- Tracking these markers after a clinician-guided hormone, thyroid, or vitamin D intervention
- Looking for hormone-related context after nutrition and activity changes have not explained your progress
- HSA/FSA eligible
- Results delivered to your dashboard · Reviewed by a real clinician
Pre-test considerations
No fasting is required. Cortisol and several sex hormones change across the day, so follow any timing instructions from your care team and use a similar collection time for repeat tests. Hydrate, collect while seated, and return the labeled sample and completed form the same day, Monday through Friday.

What this test is for
This panel measures cortisol, DHEA-S, TSH, vitamin D, albumin, and several sex-hormone markers. These results can add context when weight changes occur alongside fatigue, sleep disruption, menstrual changes, low libido, or changes in recovery and body composition. The panel does not measure glucose, insulin, or HbA1c, so it is not a complete metabolic or diabetes assessment. No single hormone result can establish why weight changed.
Biomarkers tested

Albumin is the protein your liver churns out in the largest quantity, and it does double duty: it holds water inside your blood vessels (so fluid doesn't leak into tissue) and ferries hormones, fatty acids, and medications through your bloodstream. Low albumin points to liver disease, kidney protein loss, chronic inflammation, or poor nutrition, and often shows up alongside swelling, fatigue, or unexplained weight loss. Because it reflects both liver production and overall protein status, it's a useful baseline check and a quick way to see whether inflammation or malnutrition is quietly dragging your protein reserves down.

Cortisol is the hormone your adrenal glands release to manage stress, blood sugar, blood pressure, and your wake-sleep rhythm, peaking in the morning and tapering through the day. High levels can point to chronic stress, Cushing's syndrome, or overtraining, while low levels suggest adrenal insufficiency (Addison's disease) or a pituitary problem, either of which can drive fatigue, weight changes, poor sleep, low blood pressure, and brain fog. Testing it establishes a baseline for how your body handles stress and helps investigate unexplained exhaustion, mood swings, or a sleep-wake cycle that feels out of sync, especially when paired with ACTH or DHEA-S for fuller context.

DHEA-S is made almost entirely by the adrenal glands and serves as a stable reservoir your body converts into testosterone and estrogen as needed, making it a reliable read on adrenal androgen output since it doesn't fluctuate hour to hour like cortisol. Low levels can accompany fatigue, low libido, reduced muscle mass, and mood changes, and often show up with adrenal insufficiency or normal age-related decline, while high levels point toward PCOS or an adrenal disorder and often come with acne, excess hair growth, or irregular cycles. It's a useful baseline for tracking adrenal and hormonal aging over time, and a key piece alongside testosterone and cortisol when investigating unexplained fatigue or hormonal symptoms.

Estradiol is the dominant estrogen, produced mainly by the ovaries, and it governs the menstrual cycle, builds the uterine lining, supports bone density, and helps regulate mood and sleep. In women, this test tracks ovarian reserve and cycle phase, monitors fertility treatment, or investigates irregular periods, hot flashes, night sweats, low libido, or mood shifts around perimenopause and menopause. In men, estradiol is made from testosterone and, when elevated, can drive gynecomastia, low libido, or mood changes, so it's often checked alongside testosterone when those symptoms show up or when starting hormone therapy.

- Serum or plasma
- Measures
- Mass concentration
Progesterone rises after ovulation to signal the uterine lining to prepare for pregnancy, then falls if no pregnancy occurs, which triggers your period. Testing it confirms whether ovulation actually happened that cycle, useful when tracking fertility, investigating irregular or absent periods, or explaining PMS-like symptoms such as mood swings, bloating, and breast tenderness. In early pregnancy, low progesterone helps explain risk of miscarriage, while timed testing (roughly a week before your expected period) gives the clearest read on ovulatory function.

- Mass concentration
SHBG is a liver-made protein that binds testosterone and estradiol, controlling how much hormone is free to act on tissue rather than locked up in transit. High SHBG (common with high estrogen, hyperthyroidism, or liver disease) can leave you hormonally starved even when total testosterone looks normal, while low SHBG (seen with insulin resistance, obesity, or hypothyroidism) inflates free hormone activity. Pairing SHBG with total testosterone gives you an actual free testosterone picture, useful for investigating low libido, fatigue, mood changes, or irregular cycles, and for tracking how weight loss or metabolic changes are shifting your hormone availability over time.
- Specimen
- Serum or plasma

- Substance concentration
Total testosterone measures the hormone your testes (or ovaries and adrenal glands in women) produce to drive libido, muscle mass, bone density, energy, and mood. Low levels show up as fatigue, low sex drive, harder recovery from training, mood changes, and difficulty building or keeping muscle, while high levels in women can signal PCOS or point to an androgen-secreting source. It is the standard baseline for anyone tracking hormonal health with age, evaluating symptoms, or checking response to training, weight loss, or testosterone therapy.

TSH is the pituitary's signal to the thyroid, rising when it senses too little thyroid hormone in circulation and falling when there's too much. High TSH points to an underactive thyroid, often behind fatigue, weight gain, cold intolerance, constipation, dry skin, and low mood. Low TSH points to an overactive thyroid, showing up as anxiety, racing heart, weight loss, heat intolerance, or sleep trouble, and it's the single most sensitive marker for catching thyroid dysfunction before it fully unravels your energy, weight, and cycle.

Frequently asked questions
View all FAQsIs this kit right for me?
The Tasso+ collector is intended for adults 18 and older. Use it while seated. People taking blood thinners may experience prolonged bleeding after collection. If you have questions about at-home blood collection, speak with a clinician before using the kit.
Do I need a lab appointment?
No. Your kit is delivered to your door and you collect the sample at home. There is no lab visit or venipuncture.
When should I collect and return my sample?
Plan to collect Monday through Friday, on a day when you can drop the prepaid return at a FedEx store that same day. Check your local FedEx hours before you begin.
What is included in the kit?
Your kit includes the single-use collector, collection materials, step-by-step instructions, and prepaid return packaging. The in-box guide covers the handling and packing details.
When will I get my results?
Your results post to your dashboard once the lab completes them. Specialty assays and at-home kits can take longer, and the expected turnaround is shown before you buy.
