As new lab tests are completed, your results are integrated into your electronic medical record, so your physician can access your complete medical history efficiently.

Our highly trained technicians communicate directly with your healthcare providers to answer questions about your test results. We provide a range of lab testing services, including blood draws and specimen handling, for tests involving:

  • Chemistry
  • Hematology
  • Coagulation
  • Urinalysis
  • Microbiology
  • Transfusion services

Bone density screening (DEXA)

Bone density screening, also called dual-energy X-ray absorptiometry (DEXA), or bone densitometry, is an enhanced X-ray that measures bone loss. At Portsmouth Regional Hospital, we offer the Hologic bone densitometer, the most accurate method available for diagnosing bone density loss.

A DEXA scan is most often used to diagnose osteoporosis, a condition that generally affects women after menopause but may also be found in men. Bone density screening assesses your risk for developing fractures. A DEXA screening is a simple, quick and noninvasive procedure that needs no anesthesia. The amount of radiation used is extremely small—less than one-tenth the dose of a standard X-ray and less than a day's exposure to natural radiation.

Your or your doctor can call (603) 559-4190 for more information or to schedule your bone density screening.

Stereotactic biopsy

Stereotactic biopsy is a procedure that assists in the diagnosis of cancerous cells in breast tissue. During this procedure, a radiologist uses images of the breast tissue to take a sample for testing. This is less invasive than a surgical biopsy, leaves little to no scarring and helps evaluate tiny masses not visible on an ultrasound. All biopsies are offered on an outpatient basis and are available for same-day appointments.
