Lymphoproliferative investigation (Peripheral blood lymphocytosis, CLL, Lymphoma)

Haematology


Description

The lymphoproliferative protocol is performed on patients presenting with a peripheral blood lymphocytosis, or patients presenting with clinical symptoms, who are suspected of having a malignant B or T lymphoproliferative disorder. Testing is performed on blood if there are abnormal circulating cells or bone marrow otherwise. The aim is to demonstrate a monoclonal population and classify the underlying lymphoproliferative disorder. The lymphoproliferative workup consists of a detailed morphology report, membrane immunofluorescence and surface membrane immunoglobulins. All of which are essential in establishing a diagnosis.


Indications

Unexplained lymphocytosis or if patient presents with symptoms suggestive of a lymphoproliferative disorder.


Sample Type

Whole Blood/Bone marrow ( EDTA 4.0 ML ), Date and time of collection to be written on sample.

Turnaround Time

A verbal interim result is usually available within 24 hours of sample receipt if the lab is contacted in advance and a contact name and number is given. 5 working days for validated report.
