Lung Cancer, EGFR with ALK Reflex, Tumor

Specimen Type Describes the specimen type needed for testing


Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

Pathology report must accompany specimen in order for testing to be performed.



1. New York Clients-Informed consent is required. Please document on the request form or electronic order that a copy is on file. An Informed Consent for Genetic Testing (Supply T576) is available in Special Instructions.

2. If not ordering electronically, complete, print, and send a Oncology Test Request Form (T729) with the specimen (



Specimen Type: Tissue

Container/Tube: Tissue block

Collection Instructions: Submit a formalin-fixed, paraffin-embedded tissue block.



Specimen Type: Tissue

Container/Tube: Slides

Specimen Volume: 12 unstained, unbaked slides or 2 hematoxylin and eosin-stained slides (will not be returned) and 10 unstained, unbaked slides

Collection Instructions: Submit 12 unstained, unbaked slides cut at 5-microns or 2 slides stained with hematoxylin-and-eosin and 8 unstained, nonbaked slides with 5-micron thick sections of the tumor tissue.

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.

Formalin-fixed, paraffin-embedded tissue block (preferred) or 2 slides stained with hematoxylin- and- eosin and 10 unstained, nonbaked slides with 5-microns thick sections of the tumor tissue.

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected

Note: No specimen should be rejected. If specimen not received at appropriate temperature or in wrong anticoagulant, include note to laboratory. If questions, contact laboratory.

Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
