Services and Procedures - CTTS


It is the policy of our Department to retain all tissue blocks, so to satisfy investigators with indispensable material for research or clinical trial, we offer the following:

  • Paraffin-embedded tissue block cores ranging from 1 mm to 4 mm
  • Paraffin-embedded tissue block cores that are re-embedded into a labeled tissue block
  • Paraffin-embedded recut slides at thickness requested
  • Paraffin-embedded recut slides that are H&E stained


For each work request, a standard CTTS Work Request form must be completed by the requesting investigator. The completed form gives us your ordering and shipping information and charging instructions, as well as patient-requested tissue specifications. CTTS strives to complete all requests within a time sensitive manner.

Please email all Clinical Trial Tissue Service requests to or fax to (203) 737-8388.
