8 Best Blood Testing Clinics in New York City (2026)

Patients Medical has operated as an integrative health care center on Fifth Avenue in New York City since 1974, making it one of the longest-established functional medicine practices in the United States. The clinic is led by Medical Director Dr. Rashmi Gulati MD, who has directed the practice since 2004, supported by a multidisciplinary team including Dr. Emine Cosar (gynecologist and obstetrician), Dr. Kulsoom Baloch, Dr. Stuart Weg MD, and John Pillepich PhD CPhT (clinical pharmacist). The practice is cash-pay only and explicitly does not accept insurance, allowing physicians to spend extended time with each patient and build highly individualized treatment protocols. The clinic's therapeutic focus spans intravenous nutrition and infusion therapy — including general vitamin cocktails, NAD+ infusions, glutathione, high-dose vitamin C, and specialty protocols for immune support, detoxification, energy, and migraine relief — as well as ozone therapy in multiple modalities (standard ozone, EBOO/10-pass, UV blood irradiation), EDTA chelation therapy for heavy metal detox and cardiovascular support, and bioidentical hormone replacement therapy with full hormone, adrenal, and thyroid testing. The in-house functional medicine laboratory offers an unusually broad panel of diagnostics: CBC, comprehensive metabolic panel, heavy metal testing, genetic and methylation analysis, allergy panels, organic acid testing, neurotransmitter testing, Lyme disease, mold, fatty acid, amino acid, and fertility testing. Financing is available through CareCredit for qualified patients.
