Several service areas in the Unit for Laboratory Animal Medicine (ULAM) will be closed or operating at limited capacity during the upcoming holiday season.

Both ULAM Pathology Core locations at NCRC and MSAB will be closed beginning at 12:00 PM (noon) on Friday, December 22, 2023 โ€“ Monday, January 1, 2024.

Sample submission deadlines BEFORE the holidays are as follows:

  • Monday, December 18 โ€“ for histology
  • Wednesday, December 20 โ€“ for hematology/chemistry/send-outs

These deadlines were chosen to allow ULAM Pathology Core staff sufficient time before the holiday break to process samples to a stable stage. CBCs must be completed within 24 hours of receipt, and paraffin histology samples are stable once they reach the embedding stage.

Samples that do not need processing prior to the holidays (frozen serum, glass slides, paraffin blocks) can be submitted by appointment up until the closing date; no work will be done during the time period that the ULAM Pathology Core is closed.

As a reminder, sample submission is by appointment only. Study teams are strongly encouraged to book their appointments early, particularly if they anticipate a large submission, in order to help ULAM Pathology Core staff plan their workflows accordingly.

Both ULAM Pathology Core locations will re-open on Tuesday, January 2, 2024, at 9:00 AM.
