ULAM Pathology Core Sample Submission Deadline for the Thanksgiving Holiday

11/25/2026 12:00 pm

ULAM Pathology Core

ULAM’s Pathology Core will be closed beginning at 12:00 PM (noon) on Thursday, November 26 – Friday, November 27, 2026, in observance of the U-M’s Thanksgiving holiday.

To ensure that your research needs are met quickly and efficiently, please review and share these deadlines with your team, plan ahead, and act early.

Sample submission deadlines BEFORE the holiday are as follows:

  • 12:00 PM on Tuesday, November 24 – for histology
  • 12:00 PM on Wednesday, November 25 – for hematology/chemistry/send-outs
  • 4:00 PM on Friday, October 30 – for immunohistochemistry*

These deadlines were chosen to allow Pathology Core staff sufficient time before the 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.

*Immunohistochemistry submissions are closing early (end of October) due to low staffing. These submissions require the longest workflow and longest turn-around times.

Samples that do not need processing prior to the holiday (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 Pathology Core staff plan their workflows accordingly.

Both ULAM Pathology Core locations will re-open on Monday, November 2 at 9:00 AM.
