13q FISH

Also known as: 13q FISH

« Back to test list

Purpose

Deletions affecting the long arm of chromosome 13 can be found in a number of mature B-cell lymphoid neoplasms, particularly chronic lymphocytic leukaemia (CLL), and also splenic marginal zone lymphoma and mantle cell lymphoma. Testing provides information regarding prognosis.

Clinical Utility

Presence of a 13q deletion is a positive prognostic sign in CLL.

This is an assay for non-heritable mutations. It does not raise issues of ethics or consent that are different from most other investigations ordered in the routine care of a patient.

Genes

Not specified

Test Method

Fluorescent in situ hybridisation (FISH) analysis, using probes located within 13q.

Test Ordering

This test is usually requested by a haematologist or oncologist.

0.5 mL bone marrow in transport media, or 5-10 mL blood in lithium heparin.

To help ensure the quality of the test, a genetic test should be done with a dedicated sample whenever possible i.e. a sample collected specifically for that test rather than a sample that is used for multiple tests.

We also recommend that the patient or another adult check the labelling of request forms and sample tubes.

Price

$205 - $255

The price varies according to the specific clinical conditions for a particular patient. Please contact Sonic Genetics on 1800 010 447 for more information.
