Hematopoiesis

Hematopoiesis

The process of blood cell formation is called hematopoiesis. Hematopoiesis starts early during development, on the seventh day of embryogenesis. This phase of hematopoiesis is called the primitive wave, wherein the extraembryonic yolk sac allows the production of erythroid cells and endothelial cells from a common precursor called hemangioblast. The erythroid cells provide oxygen to support the growth of the rapidly dividing embryo. Hemangioblasts later develop into hematopoietic stem cells or...

Summary

This summary is machine-generated.

Malaysian full blood count (FBC) reference intervals differ significantly from other populations, highlighting the need for locally derived guidelines. Iron deficiency is a key cause of anemia across Malaysian demographics.

Area of Science:

Hematology
Clinical Biochemistry
Population Health

Background:

Current Malaysian full blood count (FBC) reference intervals are often based on non-Malaysian data.
Significant inter- and intra-population variations necessitate population-specific intervals.

Purpose of the Study:

To establish population-specific reference intervals for full blood count parameters in Malaysia.
To investigate demographic influences (age, sex, ethnicity) on haematological parameters.

Main Methods:

Recruited 2,725 healthy Malaysian adults across diverse demographics.
Performed FBC using Sysmex XE-5000 and Unicel DxH 800 analysers.
Conducted statistical analysis to determine reference intervals and subgroup estimates.

Main Results:

Established Malaysian-specific reference intervals, revealing significant differences in haemoglobin, RBC count, platelet count, and haematocrit compared to international standards.
Observed variations in haematological parameters based on sex and age, with unique findings for haemoglobin in women.
Identified iron deficiency as a primary contributor to anemia in Malaysian women and men.

Conclusions:

Validated the critical need for Malaysian-specific haematological reference intervals.
Advocates for the development of local guidelines over generalized reference values.
