Where tests are usually done on clinical specimens in order to obtain information about the health of a patient as pertaining to the diagnosis, treatment, and prevention of disease. Our pathology and laboratory workforce comprises of qualified and experienced personnel and current instruments and equipment are used. Speed and accuracy are critical in diagnosis and administration of the right counsel and treatment to a patient. The delivery of test results are benchmarked against specified Turnaround time (TAT).

All tests are conducted by qualified senior laboratory scientist. Reports are provided by experienced and highly qualified cytogeneticists, Dr. Roziana Ariffin.

We offer wide selection of chromosome karyotyping and fluorescence in situ-hybridization (FISH) tests. All our tests are reported in accordance to the International System for Human Cytogenetics Nomenclature (ISCN, 2016).

We provide the following services:

  1. Constitutional karyotyping (cord blood / foetal blood, peripheral blood0
  2. Prenatal karyotyping (amniotic fluid)
  3. Tumour karyotyping (bone marrow)


a) Bone Marrow Karyotyping

2 ml bone marrow specimen preferably from the first or second aspiration in sodium heparin / lithium heparin vacutainer tube.

b) Blood Karyotyping

5ml peripheral blood (>10% blasts) in sodium heparin / lithium heparin vacutainer tube if the bone marrow aspiration is not successful.


a) Amniotic Fluid (AF) Karyotyping

15-20ml of AF in sterile conical (v-shape) tubes. Discard the first 2ml on sampling.


a) Peripheral Blood Karyotyping

  • 3-5ml of Peripheral blood in sodium heparin / lithium heparin (green tap) vacutainer tube. Do not use EDTA.
  • For newborns, collect a minimum of 1ml peripheral blood in sodium heparin / lithium heparin vacutainer tube.
  • For deceased patients, 3-5ml blood collected by cardiac puncture (within 1 hour of death) in a sodium heparin / lithium heparin vacutainer tube.

b) Peripheral Blood Constitutional FISH

  • Microdeletion syndromes (please contact laboratory in advance for probe availability).
