Pathology Consult, Hematology/Smear Review (Southeast Michigan Only)

Pathologist Consult

Test Codes

EPIC LAB1231496

Add on: Pathologist Review, Blood Smear for Consult (no CBC): LAB1231501

Department

Hematology

Instructions

• Includes CBC with Differential, Reticulocyte Count, and Pathologist Consultation.
• Orders for Hematopathologist Consult for morphology review MUST contain an established diagnosis or signs/symptoms. All Path Consult requests must have the applicable diagnosis code entered into EPIC/Laboratory Information System (LIS) upon order entry. While Rule Out (R/O) is often a useful way to communicate your suspicion to the consulting hematopathologist, it is NOT sufficient. 
• It is also essential when ordering Hematopathologist Consults to avoid using the word "Hemogram". A hemogram is a simple CBC w/o platelet count or differential and is not synonymous with a consult. If a Hematopathologist Consult is required, please so indicate.

Specimen Collection Criteria

Collect (preferred specimen): One 4.0 mL Lavender-top K₂EDTA tube. (Minimum: 2.0 mL)
Also acceptable: One Lavender-top K₂EDTA Microtainer^®. (Minimum: 300 mcL)
See Minimum Pediatric Specimen Requirements for Microtainer^® collection.

A copy of the requisition must be sent with the specimen.

Physician Office/Draw Specimen Preparation

Maintain specimens refrigerated (2-8°C or 36-46°F) prior to transport. Room temperature (20-26°C or 68-78.8°F) is acceptable for a maximum of 8 hours.

Preparation for Courier Transport

Transport: Whole blood or capillary blood, refrigerated (2-8°C or 36-46°F). (Minimum: 2.0 mL whole blood or 300 mcL capillary blood)

Rejection Criteria

• Specimens containing clots.
• Insufficient volume.
• Frozen specimens.
• Centrifuged specimens.
• A slide review to the pathologist must be ordered as a Pathology Consult.
• In order to ensure compliance with Medicare and other federal regulatory agencies, the Hematology Laboratory has instituted the written policy of not accepting requests for pathologist consultation to review normal CBC/Differential results.
• Due to the deterioration of morphology on aged specimens, it is not appropriate to add a Path Consult to an EDTA specimen that was collected more than 24 hours prior. All requests for an add-on Path Consult should be re-directed at obtaining a fresh specimen.
• Duplicate orders for a Path Consult within a 7-day time frame will not be accepted.
