What is the composition of the buffy coat in centrifuged blood sample?

The buffy coat in a centrifuged blood sample consists of:

White Blood Cells (Lymphocytes)

White blood cells, specifically lymphocytes, are found in the buffy coat. These cells play a crucial role in the immune system, defending the body against infections and diseases.

Platelets

Platelets, also known as thrombocytes, are tiny blood cells that help in the clotting process to stop bleeding. They are present in the buffy coat of a centrifuged blood sample.

The buffy coat is a thin, creamy white layer located between the yellowish plasma and the red blood cells in a centrifuged blood sample. It makes up a small percentage (less than 1%) of the total blood volume.
