Test ID: LN    
Chromosome Analysis, Lymphoid Tissue

Specimen Type Describes the specimen type needed for testing

Tissue

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.

Provide a reason for referral with each specimen. The laboratory will not reject testing if this information is not provided, but appropriate testing and interpretation may be compromised or delayed. Include pathology reports, if available.

 

Preferred: Lymphoid tissue

Acceptable: Spleen, extranodal tissue

Container/Tube: Sterile container with sterile Hank's balanced salt solution (Supply T132), Ringer's solution, or normal saline

Specimen Volume: 1 cm(3)

Additional Information:

1. Advise Express Mail or equivalent if not on courier service.

2. Spleen tissue or extranodal tissue may be submitted when a lymphomatous disorder is believed to involve these tissues.

Forms: If not ordering electronically, submit a Cytogenetics Hematologic Disorders Request Form (Supply T607) with the specimen.

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.
