Northwell Health provides pathology and laboratory services 24 hours a day, seven days a week. The laboratories provide comprehensive and routine testing of specimens across the health system. Pathologists help diagnose disease, determine its causes, and monitor diseases from common condition to complex infections. We also provide second opinions and subspecialty consultations for patients. 

Lenox Hill Hospital has a full-service laboratory providing services in clinical and anatomic pathology.

Our physicians, scientists, laboratory technicians, lab assistants, biologists, chemists, geneticists and other specialists work collaboratively to examine and diagnosis specimens. We have 13 board-certified pathologists and more than 175 laboratory specialists who perform over one million laboratory tests annually – including more than 23,000 surgical specimens per year.

The laboratory also supports an ACGME-approved 4-year residency training program in anatomic and clinical pathology under the direction of Samuel J. Wahl, MD. For more than 50 years, the program has trained pathologists in surgical pathology, hematopathology and autopsy services.

Clinical Expertise

Clinical laboratories

The clinical laboratory at Lenox Hill Hospital offers comprehensive testing options for standard and specialized procedures. Our testing in the areas of chemistry, hematology and microbiology is designed to support the various specialties offered by Lenox Hill Hospital physicians and practice physician throughout the region. 

Utilizing state-of-the-art equipment, the department is staffed by a team of highly qualified New York State-licensed laboratory professionals. The laboratory operates 24 hours a day, 7 days a week and provides testing on a routine and STAT basis to both in-patient and out-patient populations.

Cytopathology laboratory

The Lenox Hill Hospital Cytopathology Service plays a prominent role in the diagnosis and treatment of benign and malignant conditions. Cytology specimens are prepared and evaluated on-site at Lenox Hill by an experienced staff of cytotechnologists and board-certified cytopathologists. 

We work closely with primary care physicians, radiologists, surgeons, and oncologists helps to assure timely and accurate results. The cytopathology service also offers consultation for second opinions on diagnostically challenging cytologic material. We also provides rapid on-site evaluation for bronchoscopy and gastrointestinal endoscopic procedures.  

Together with the Lenox Hill Radiology Department the Cytopathology Service performs and assesses fine needle aspiration biopsy procedures for both superficial and deep-seated lesions. Commonly aspirated body sites include:

  • Abdomen
  • Breast
  • Liver
  • Lung
  • Lymph nodes
  • Salivary gland
  • Soft tissue 
  • Thyroid

These minimally invasive procedures are less traumatic for the patient and may obviate the need for more costly surgery.  Most are done in an ambulatory setting using ultrasoundCT and fluoroscopic imaging.  Samples are collected and immediately evaluated on site for specimen adequacy. 

Out-patient and pre-operative testing

Out-patient and pre-operative testing is offered at the Raisler Testing Center on the third (3rd) floor of the main hospital building. Testing is available Monday - Friday, 8:00 a.m. - 6:00 p.m. Pre-operative and specialty testing appointments may be made by calling (212) 434-6057. 

Routine outpatient testing is accommodated on a walk-in basis and requires a written physician order for all tests. Fasting is not normally required unless specified by the physician. The department supports a highly skilled phlebotomy staff providing excellent service to our patients.

Surgical Pathology Service

The Surgical Pathology service, a division of anatomic pathology, processes more than 23,000 patient specimens annually. The majority of cases are from surgeries performed at Lenox Hill Hospital and Manhattan Eye, Ear and Throat Hospital, as well as specimens sent from physician practices in the surrounding area.  

The Surgical Pathology Service operates Monday – Friday, 8:00 a.m. to 6:00 p.m. and Saturdays from 8:00 a.m. to 1:00 p.m.  24-hour coverage for emergency intra-operative diagnosis is provided 7 days a week by a staff pathologist on call.  The service is staffed bytwelve board certified pathologists with subspecialty expertise in pathology of the breast, hematologic disease, lung, urogenital tract, gastrointestinal tract, pancreas and liver, kidney, head and neck, soft tissue, and endocrine system. 

As an integral part of Northwell Health’s Pathology and Laboratory Medicine department, we offer additional expertise in dermatopathology and pediatric pathology.
