At-Home TRT Monitoring Test Kit
A focused monitoring panel for testosterone therapy, including hormone balance and red blood cell markers.
Consider this test if:
- Completing scheduled laboratory monitoring for prescribed testosterone therapy
- Checking total and free testosterone alongside SHBG, estradiol, LH, and prolactin
- Monitoring hemoglobin and hematocrit during ongoing testosterone treatment
- Comparing results after a clinician-directed dose, formulation, or schedule change
- HSA/FSA eligible
- Results delivered to your dashboard · Reviewed by a real clinician
Pre-test considerations
No fasting is required. Follow your prescriber's instructions for timing the sample relative to your testosterone dose, since the correct timing depends on the formulation and schedule. Use the same dose timing for repeat tests when possible. Hydration can affect hemoglobin and hematocrit, so hydrate normally. Return the labeled sample and completed form the same day, Monday through Friday.

What this test is for
This panel measures total and calculated free testosterone, SHBG, albumin, estradiol, LH, and prolactin, plus hemoglobin and hematocrit. The hormone markers show treatment level and binding context, while hemoglobin and hematocrit help monitor changes in red blood cell concentration that can occur during testosterone therapy. Results should be reviewed with the prescribing clinician and interpreted against the medication, dose, route, and time since the last dose. The panel supports ongoing monitoring but does not replace the rest of a clinician's safety assessment.
Biomarkers tested
Includes 9 biomarkers
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.

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.

Hematocrit measures the percentage of your blood volume made up of red blood cells, the cells that carry oxygen from your lungs to every tissue. Low hematocrit points to anemia and pairs with fatigue, breathlessness, dizziness, or poor exercise tolerance, while high hematocrit can reflect dehydration, high altitude, smoking, or overactive red cell production, and thickens blood in ways that matter for cardiovascular risk. It's a core piece of the complete blood count, useful as a baseline read on oxygen-carrying capacity and for tracking how iron status, training, or altitude exposure are shifting your blood over time.

LH is the pituitary signal that triggers ovulation in women and drives testosterone production in the testes of men, acting as the messenger between brain and gonads. In women, tracking LH alongside FSH and estradiol clarifies where you are in your cycle, confirms ovulation timing for fertility planning, and helps investigate irregular periods or suspected PCOS. In men, a low LH with low testosterone points to a signaling problem upstream in the pituitary, while a high LH with low testosterone points to testicular failure, a distinction that changes how low libido, fatigue, or muscle loss get treated.

Prolactin is made by the pituitary gland and its main job outside of pregnancy and lactation is to signal, so elevated levels suppress the reproductive hormones that drive libido, ovulation, and testosterone production. High prolactin shows up as irregular or missing periods, unexplained milk production, low libido, erectile dysfunction, or fertility difficulty, and can stem from certain medications, thyroid problems, stress, or a pituitary adenoma. If you're investigating a stalled cycle, unexplained galactorrhea, low libido, or working through a fertility workup with estradiol, FSH, and LH, prolactin tells you whether this hormone is the one crowding out the others.

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.

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.

A blood sample, without the lab visit
This kit uses a single-use Tasso+ collector on your upper arm. A small puncture and gentle vacuum collect a capillary blood sample, so there is no venipuncture or lab appointment.
Needle-free convenience
A more comfortable alternative to a traditional blood draw, and designed to reduce discomfort compared with finger sticks or venipuncture, for a more comfortable lab experience.
Pre-paid shipping (both ways)
Your kit is shipped to your door, and a prepaid FedEx return label is included to send your sample back.

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.
