Hematopathology, Blood or Bone Marrow

Hematopathology, Blood or Bone Marrow (HCPATHH) Hematology Lab Test

Name: Hematopathology, Blood or Bone Marrow

Test Name: Hematopathology, Blood or Bone Marrow

Health Link Test Code: HCPATHH

LIS Test Code: PATHH

CPT Code(s): 85097-Bone Marrow; 85060- Blood

Test Component:

May include CBC with differential, Reticulocyte count, Flow Cytometry, Bone Marrow differential and interpretation by hematopathologist.

Days Performed: Mon-Fri.

Stat In-Lab Turnaround Time: 2 - 3 days.

Specimen: Blood or bone marrow

Collection Instructions:

Blood specimens- A lavender-K3EDTA tube is preferred for CBC and Differential results. A lavender-K2EDTA tube is acceptable. Two unstained smears should accompany the specimen.


Bone Marrow Specimens- CBC with Differential and reticulocyte count must be ordered in conjunction with bone marrow collection. Bone marrow specimens are collected by a physician at the bedside and coverslip smears are prepared by the laboratory technologist. If a bone marrow biopsy is collected it is put in a vial containing Z-5 fixative (note time the biopsy was put into the Z-5 on the vial and on the form).


Outreach- Bone marrow aspirate specimens for morphologic assessment should be directly smeared onto clean coverslips/slides made from a non-anticoagulated bone marrow aspirate (allow to air dry). Extra bone marrow aspirate should be put into a heparin (green) top tube. Refer to the individual tests for collection instructions for non-morphologic tests (eg. cytogenetics, flow cytometry, molecular, etc).

Stability Ambient:

Unfixed slides are stable for 7 days

Outreach Specimen Processing:

Transport specimens at ambient temperature. Put coverslip slides into a manilla coin envelope and label with two patient identifiers (name and birthdate), date and time of collection. Put envelope into a plastic container to protect the slides during transport. Put the bone marrow biopsy that is in Z-5 fixative in a biohazard bag and seal it. Do NOT put slides in the same bag as the Z-5 fixative. Put all the specimens and form into one larger bag and transport to UWHC Hospital Laboratory ASAP.

Additional Information:

A hematopathologist's written interpretive report is issued as a separate report.
