Recommendations for cytogenomic analysis of hematologic
What is the preferred sample for the cytogenetic analysis for the diagnosis of leukemia?
Bone marrow tests.
A bone marrow sample may be taken from the hipbone and studied by pathologists to determine whether leukemia cells are present.
Why is cytogenetics important in hematology?
Cytogenetic analysis has demonstrated that haematological neoplasms result from a somatic mutation occurring in a haemopoietic, lymphoid or multipotent stem cell.
What are the indications for cytogenetic analysis?
The main indications of cytogenetic studies in congenital genetic diseases are: Abnormal ultrasound findings.
Abnormal biochemistry results.
Recurrent miscarriages.
- During karyotyping, cells are taken from a blood or bone marrow sample and stained with special dyes.
Then pictures are taken of the cells under a microscope.
This process is performed by a pathologist, a geneticist, or a cytogenetics technician.
They line up all of the chromosomes into pairs of 23 and count them.
