Testing Algorithm
Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

This test is designed to hold the sample and delay fluorescence in situ hydribization (FISH) testing while preliminary morphologic assessment or flow cytometry testing is in process.

 

Hold policy: Upon sample receipt, the specimen will be held in the laboratory. FISH testing will not be performed unless the client contacts the laboratory and indicates that FISH testing is desired. The client must contact the Cytogenetics Laboratory at 800-533-1710 by 4 p.m. (Central time) no later than 4 business days (96 hours) after the specimen was collected. If no notification is received by this time, the order will be processed as "cancelled." Weekend communication can be deferred until Monday.

Specimen Type
Describes the specimen type validated for testing

Varies

Ordering Guidance

This test is designed to hold blood and bone marrow specimens only.

 

This test does not apply to chromosome analysis. If specimen is to be held for chromosome analysis, order HOLDC / Hematologic Disorders, Chromosome Hold, Varies.

 

Due to stability issues, test PCPDS / Plasma Cell Proliferative Disorder, High-Risk with Reflex Probes, Diagnostic FISH Evaluation, Bone Marrow cannot be added onto specimens held under this test.

Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test

Fluorescence in situ hybridization (FISH) analysis using gene-specific probes is a useful methodology to detect common, recurrent chromosome abnormalities for most hematologic malignancies. Based on morphologic review of the bone marrow or peripheral blood specimen by a hematopathologist, a determination of additional appropriate testing can be made. If the specimen does not show evidence of malignancy, FISH analysis may not be necessary. Depending on the diagnosis, conventional chromosome analysis may also be more informative.

Reference Values
Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.

Not applicable

Interpretation
Provides information to assist in interpretation of the test results

If notified by the client, this test may be canceled, and a processing fee will be assessed.

 

If no notification to proceed with testing is received, this test will be reported as "cancelled."

Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

Day(s) Performed
Outlines the days the test is performed. This field reflects the day that the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time before the test is performed. Some tests are listed as continuously performed, which means that assays are performed multiple times during the day.

Monday through Sunday

Report Available
The interval of time (receipt of sample at Mayo Clinic Laboratories to results available) taking into account standard setup days and weekends. The first day is the time that it typically takes for a result to be available. The last day is the time it might take, accounting for any necessary repeated testing.

4 days

Specimen Retention Time
Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

4 weeks

Performing Laboratory Location
Indicates the location of the laboratory that performs the test

Test Classification
Provides information regarding the medical device classification for laboratory test kits and reagents. Tests may be classified as cleared or approved by the US Food and Drug Administration (FDA) and used per manufacturer instructions, or as products that do not undergo full FDA review and approval, and are then labeled as an Analyte Specific Reagent (ASR) product.

Not Applicable
