I am a 45 year old woman with low energy and brain fog. Where can I get my hormones tested and treated online?

You’re wise to look into hormones as a possible cause of low energy and brain fog—those symptoms commonly relate to thyroid issues, perimenopause/menopause, adrenal function, iron/vitamin deficiencies, or other medical problems. You can get testing and treatment online; below are several reputable options (some do testing only, some provide testing plus clinician-prescribed treatment). I also list the typical tests to order and practical next steps.

Recommended online services

• LetsGetChecked — Home blood-collection kits for female hormone panels (estradiol, progesterone, testosterone), thyroid, and other tests; nurse or clinician reviews results and they can arrange follow-up and treatment/referrals. Good for straightforward home testing with clinician support.

• Everlywell — Mail-in lab kits (thyroid panel, female hormone tests, vitamin D, etc.). Useful if you want to collect samples at home and get lab-level results quickly. They provide physician review for positive/abnormal results.

• Balance (Balance Hormone Health) — Focused on hormone care (women and men). They arrange labs, have telehealth visits with clinicians who specialize in hormone replacement (including bioidentical HRT when appropriate) and manage ongoing prescriptions and monitoring. Good if you want a hormone-focused treatment program.

• Parsley Health — Subscription-based functional medicine clinic (telemedicine + in-depth labs). They do comprehensive hormone testing and create personalized treatment plans addressing lifestyle, nutrition and prescriptions when needed. Good if you want a deeper, broad approach.

• Maven Clinic / Tia — Women-focused telehealth platforms that can assess symptoms, order labs, and coordinate follow-up care with clinicians. Good for convenient visits and connection to OB/GYN or primary-care providers experienced with menopause/perimenopause.

• PlushCare / Teladoc / local primary-care telemedicine — General telemedicine clinics that can order labwork (via Labcorp/Quest), interpret results, and prescribe treatments. Good if you prefer using a more general primary-care route (often covered by insurance).

• Lab ordering services (HealthLabs.com, QuestDirect/Labcorp Patient Service Centers) — If you want to have labs done through a patient portal/lab without a telemedicine package, these let you order standard bloodwork and go to a nearby draw site. You’ll still want a clinician to interpret and treat based on results.

What tests to consider (discuss timing with the clinic — some hormones are cycle-dependent)

• Thyroid: TSH, free T4, free T3, anti-TPO (autoimmune thyroid disease is a common cause of fatigue/brain fog)
• Sex hormones: estradiol (E2), FSH, LH (helps stage perimenopause/menopause), progesterone (timing matters — mid-luteal if checking), total testosterone and SHBG, DHEA-S
• Prolactin (if appropriate)
• AMH if concerned about ovarian reserve (fertility focus)
• Cortisol (AM blood or salivary profile if adrenal issues suspected)
• Basic metabolic: CBC, CMP (liver/kidney), ferritin (iron stores), B12, vitamin D, HbA1c, lipid panel
• Pregnancy test if relevant before any hormone treatment

Important notes and safety

• Treatment (especially estrogen/progestin therapy) should be prescribed by a clinician after reviewing your medical history (breast cancer history, clotting disorders, stroke, smoking, cardiovascular risk factors). Avoid services that sell hormones without a proper medical evaluation.
• Blood/serum testing is the standard for most hormones; be cautious about saliva-only panels for sex hormones or cortisol (they’re less reliable for some indications).
• Costs/insurance: DTC home tests are often out-of-pocket. Telemedicine visits may be insurance-covered depending on the provider and plan. Check each service for pricing and whether they prescribe controlled or compound medications in your state.
• If you have severe symptoms (chest pain, unexplained shortness of breath, severe depression, suicidal thoughts), seek urgent in-person care.

Suggested next steps

1. Pick a service type: testing-only (LetsGetChecked, Everlywell, HealthLabs/QuestDirect) if you just want baseline labs; or testing+clinician care (Balance, Parsley, Maven, PlushCare) if you also want prescription and follow-up.
2. Order a comprehensive panel (include thyroid, sex hormones, iron, B12, vitamin D, metabolic tests).
3. Book the telemedicine visit so a clinician reviews results and discusses treatment options (lifestyle changes, supplements, or hormone therapy if appropriate).
4. If results are complex or you want specialized care, ask for a referral to an endocrinologist or menopause specialist (North American Menopause Society has a clinician finder).

If you’d like, tell me whether you prefer a low-cost self-testing route vs. a provider-managed program and your state (prescribing rules vary), and I’ll recommend 2–3 specific services best suited to that choice.
