Diagnostics don’t always wait for symptoms. The address 1305 York Ave #3F sits a floor above York Avenue, quietly gathering reports for private clinics and referring physicians throughout Manhattan.

Cardiac stress testing, Holter monitoring, and echocardiograms take place by appointment; lung function and bone density studies are scheduled in the same morning cluster—all on the same premises. Spirometry and treadmill stress tests form the core menu, with thyroid and parathyroid hormone assays sent out to specialty labs when needed.

Every referral arrives labeled and staged; results exit the building as typed summaries the next business day. Patients who need copies receive them printed or, by request, faxed to their physician’s office—efficient and discreet.

You’ll find the building tucked behind the 72nd Street subway stairs, easily reached by a two-block walk from the 4/5/6 trains. Call ahead to reserve your slot, or swing by their map to confirm parking garages on East 70th. A quick ring to (212) 746-6000 secures timing that fits your calendar, not theirs.
