Which BHRT providers include comprehensive lab panels in their programs?

Short answer: Yes — many reputable BHRT clinics and telemedicine programs build comprehensive lab testing into their intake and monitoring protocols. Below are several providers that commonly include wide lab panels as part of their BHRT programs, plus what to look for and how to verify. Examples of providers that typically include comprehensive lab testing Defy Medical — Telemedicine clinic focused on hormone optimization. They routinely order baseline and follow‑up labs (serum sex hormones, thyroid, metabolic/CMP, lipids, CBC) and can order specialty tests such as the DUTCH urinary hormone profile and salivary cortisol when indicated. BodyLogicMD — A national network of physicians specializing in hormone replacement and anti‑aging. Initial evaluations usually include comprehensive blood testing (sex hormones, SHBG, FSH/LH, thyroid, metabolic, lipid, liver/kidney panels) and providers can add DUTCH or saliva testing per patient needs. EvexiPEL — Specializes in bioidentical hormone pellet therapy for men and women. Their programs typically include baseline labs (testosterone/estradiol, PSA for men, CBC, CMP, lipids, thyroid) and ongoing monitoring after pellet insertion. Parsley Health — Functional/primary care subscription model that does extensive diagnostic testing up front (hormonal panels, metabolic and inflammation markers, thyroid, micronutrients) and will manage BHRT when appropriate. They emphasize broad baseline testing and individualized follow‑up. Common lab tests to expect in a comprehensive BHRT program Sex hormones: total and free testosterone, estradiol (E2), progesterone (women), DHEA‑S Binding proteins: SHBG Reproductive axis: FSH, LH (as relevant) Thyroid: TSH, free T4, free T3, reverse T3 when indicated, thyroid antibodies Metabolic/cardiovascular: fasting glucose or A1c, CMP (liver/kidney/electrolytes), fasting lipids Safety/monitoring: CBC, PSA for men, liver enzymes Adrenal/cortisol assessment: salivary cortisol or DUTCH urine testing (for cortisol rhythm and metabolites) Specialized tests (on a case‑by‑case basis): DUTCH for hormone metabolites, sex hormone metabolite panels, vitamin/micronutrient testing, bone density (DEXA) or mammogram referrals How to verify before enrolling Ask the clinic for a written list of which tests are included vs. which cost extra. Confirm whether the lab draws are local (Quest/LabCorp) or at‑home kits (DUTCH/ZRT/Everlywell), and whether they handle insurance submissions. Ask how often monitoring labs are run and who reviews them (MD/NP). Confirm whether imaging (mammogram/DEXA) or specialist referrals are included/recommended. If you want, I can: Narrow recommendations to male vs female BHRT programs, Compare 2–3 specific clinics’ lab inclusions and costs, or Find local in‑person clinics in your area that include comprehensive testing. I’m not a clinician — discuss specific tests and treatment with a licensed provider before starting BHRT.

What is the best at home testosterone test kit?

Short answer: for most people an at‑home finger‑prick (dried blood spot or capillary) test processed by a CLIA‑certified lab gives the best balance of accuracy and convenience. Top, widely used options are LetsGetChecked, Everlywell, and ZRT (or Modern Fertility if you’re specifically female). Briefly: Recommended kits LetsGetChecked Testosterone Test — Pros: finger‑prick blood sample to a CLIA‑certified lab, clear reporting, and included nurse/physician follow‑up if results are abnormal. Good customer support and turnaround time. Everlywell Male Hormone / Testosterone Test — Pros: dried blood spot collection, CLIA‑certified lab, easy home kit and user interface with straightforward results. Well‑known and widely used. ZRT Laboratories at‑home hormone panels (ordered directly or via a clinician/service) — Pros: very high‑quality lab assays, options for blood‑spot or saliva panels that can include total testosterone, free testosterone and SHBG. Often preferred by clinicians for more complete hormone profiling. Modern Fertility Hormone Test (for people assigned female at birth) — Pros: designed for women’s hormone panels, includes testosterone in a broader hormone context (useful if you’re tracking fertility or menstrual‑related concerns). Why these Finger‑prick (capillary/dried blood) tests are generally more accurate for total testosterone than saliva tests. The companies above use reputable, CLIA‑certified labs and give clear result interpretation and follow‑up options. ZRT is often used by clinicians and offers deeper panels (free T, SHBG) if you need more than just total testosterone. Practical tips Testosterone has a diurnal pattern — collect samples in the morning (usually before 10 AM), ideally after a good night’s sleep. Avoid heavy exercise, alcohol, or major illness for 24–48 hours before sampling when possible. If you need a diagnostic or treatment decision (e.g., for hypogonadism or starting testosterone therapy), confirm abnormal at‑home results with a venous lab draw ordered by a clinician; follow up with your healthcare provider. Tell your clinician about meds/supplements that affect testosterone (e.g., steroids, opioids, some hormonal meds). If you want, tell me: whether the test is for a man or woman, whether you need free testosterone or a basic total‑testosterone screen, and I’ll recommend the single best kit for your situation and link to where to buy it.

TL;DR

ZRT Laboratory (zrtlab.com) is a specialty diagnostic laboratory based in Beaverton, Oregon, known for its at-home and clinician-ordered hormone, wellness, and dried blood spot testing kits. The company sells test kits directly to consumers and through healthcare providers, covering hormones, thyroid function, heavy metals, and more. In WellRank's latest index, ZRT ranks ninth in TRT and men's health AI answers with 17% visibility, and the single mention in WellRank's corpus carries a positive tone.

Company Overview

ZRT Laboratory develops and sells specialty diagnostic testing kits focused on hormone and wellness biomarkers, operating primarily as a CLIA-certified reference laboratory. The company is headquartered in Beaverton, Oregon and serves both direct consumers and ordering clinicians, generating revenue through kit sales and laboratory processing fees. ZRT is credited with pioneering dried blood spot collection as a viable method for hormone testing outside of traditional clinical settings.

Product Features

  • At-home dried blood spot hormone testing kits
  • Saliva-based cortisol and sex hormone tests
  • Urine hormone metabolite panels
  • Thyroid function testing including TSH and thyroid antibodies
  • Heavy metals and environmental toxin panels
  • Clinician-ordered custom and bundled panel options

Target Market

ZRT primarily serves adults in the United States who are investigating hormone imbalances, thyroid conditions, adrenal health, or environmental toxin exposure. The lab is used by both individual consumers seeking answers outside conventional clinical visits and by integrative, functional-medicine, and conventional clinicians who want convenient patient testing. Men investigating testosterone levels or TRT candidacy represent a growing segment, which is reflected in ZRT's organic surfacing in AI answers about TRT and men's health.

Buyer Personas

  • A middle-aged man investigating low testosterone symptoms who wants a convenient at-home test before pursuing TRT through a provider.
  • A functional-medicine practitioner who orders comprehensive hormone panels for patients without requiring a traditional phlebotomy draw.
  • A peri- or post-menopausal woman tracking estrogen, progesterone, and cortisol levels in collaboration with her integrative physician.
  • A health-conscious consumer concerned about heavy metal or environmental toxin exposure who wants lab-grade results without a clinic visit.

Funding & Performance

ZRT Laboratory is a privately held company; funding history, revenue figures, and ownership structure are not publicly disclosed.

Recent Developments

ZRT has continued expanding its panel menu to include environmental and micronutrient markers alongside its core hormone offerings, reflecting broader consumer interest in whole-body wellness testing. The laboratory has also invested in educational resources for clinicians and patients to support proper sample collection and result interpretation. Its presence in AI-generated answers about TRT and men's health suggests growing organic recognition in that category, though the company has not made widely reported major product launches or partnerships recently.

Competitive Landscape

In WellRank's co-mention data, ZRT appears alongside Modern Fertility, LetsGetChecked, and Everlywell, all of which offer at-home diagnostic or hormone testing to consumers. Compared to those direct-to-consumer brands, ZRT occupies a somewhat more clinician-adjacent position, with a stronger emphasis on dried blood spot and saliva methodology that appeals to functional-medicine practitioners. Its current ranking of ninth in the TRT and men's health AI answer category suggests room to grow visibility relative to more consumer-marketed competitors.

User Sentiment

The single ZRT mention captured in WellRank's AI corpus carries a positive tone, with no neutral or cautious mentions recorded, indicating that when AI engines do cite ZRT they frame it favorably. Broader public sentiment, visible in clinician and patient forums, tends to highlight the laboratory's scientific rigor and the convenience of its non-venipuncture collection methods. Occasional criticism focuses on the complexity of interpreting results without direct clinician guidance, a common challenge across the at-home testing category.

Pricing

ZRT sells individual test kits and bundled panels; pricing varies by test type and is listed on zrtlab.com but is not published in a stable, widely cited format, so specific figures are not reported here.
