The blood panel tests the following blood components for concentration:

Blood cells:

  • Red blood cells (erythrocytes)
  • White blood cells (leukocytes)
  • Platelets (thrombocytes)

Haemoglobin (the red protein responsible for transporting oxygen in the blood)
Haematocrit (the percentage of red blood cells in the blood)
