An excess of red blood cells that thickens the blood and raises clotting risk; polycythemia vera is the bone marrow disorder driving it. Blood testing detects the high hematocrit and JAK2 mutation.
Our comprehensive check-up screens for red blood cell excess (polycythemia / polycythemia vera) and hundreds of other conditions.
Basophils release histamine during inflammatory and allergic reactions.
HemoglobinHemoglobin is a protein in red blood cells that binds to oxygen in the lungs and delivers it to tissues throughout the body. It also plays a role in transporting carbon dioxide back to the lungs for exhalation.
HematocritHematocrit measures the percentage of blood volume occupied by cellular components, with the largest portion being red blood cells (erythrocytes). When blood is centrifuged, blood cells settle at the bottom, creating a visible layer that indicates their proportion relative to total blood volume.
ErythrocytesRed blood cells (erythrocytes) are the most abundant blood cells and carry oxygen from lungs to tissues throughout the body via hemoglobin. They have a biconcave disc shape that maximizes surface area for gas exchange.
