BRAF Mutation (T1799A) Analysis by PCR and Sequencing, Thyroid
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.
A pathology/diagnostic report including a brief history is required.
Thyroid lesions are required for this test.
Specimens other than fine-needle aspiration (FNA) cytology slides stained with Papanicolaou may be accepted for BRAF testing in the Molecular Genetics Laboratory. Refer to tests BRAF / BRAF Mutation Analysis (V600E), Tumor and MLBRF / MLH1 Hypermethylation and BRAF Mutation Analyses, Tumor.
Specimen Type: Thyroid lesions: FNA cytology slides stained with Papanicolaou
Container/Tube: Pathology Packaging Kit (Supply T554) requested, but not required
Specimen Volume: A minimum of 300 tumor cells total and 60% tumor cell population are required for testing. Slides may be scraped.
A quality specimen is essential for evaluation. Submit only slides containing tumor cells.
Forms: If not ordering electronically, submit a Pathology/Cytology Request Form (Supply T246) with the specimen or complete, print, and send a Oncology Test Request Form (T729) with the specimen (www.mayomedicallaboratories.com/media/customer-service/forms/oncology-request-form.pdf).
Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
