  • White blood cells, cells that fight infections
  • Hemoglobin, the protein that carries oxygen to red blood cells
  • Hematocrits, percentage of volume red blood cells occupy
  • Platelets, which aid in clotting of the blood
  • White cell differential count
  • Mean corpuscular volume, which is the mean of the red cells volumes
  • Mean corpuscular hemoglobin, which is the amount of hemoglobin present in the red blood cells
  • Mean corpuscular hemoglobin concentration, which is the hemoglobin concentration in a blood cell.

Results above or below normal may indicate that some process is not working as it should in the body.

Risks

Risks involved in performing a blood count are extremely rare. At most, there may be a hematoma at the site where blood was withdrawn. In some cases, the vein may become swollen after the blood sample is collected (phlebitis), but this can be reversed by making a compress several times a day.

People who use anticoagulant medications or have coagulation problems may suffer from a bleeding after collection. In these cases, it is important to inform the health care provider of the problem prior to collection.

Red blood cells or high hematocrits may occur due to:

Dehydration

  • Kidney disease with high erythropoietin production
  • Low blood oxygen level for a long time due to heart or lung disease
  • Polycythemia vera
  • Smoking.
  • A count of below normal red blood cells or hematocrits is called anemia. It may be due to:

Anemia

  • Autoimmune diseases such as lupus erythematosus or rheumatoid arthritis
  • Hemorrhage
  • Bone marrow failure (eg from radiation, infection or tumor)
  • Renal disease Chronic
  • Hemolysis

  • Multiple myeloma .
  • Below normal white blood cell count is called leukopenia. It may be due to:

Autoimmune diseases

  • Bone marrow insufficiency

  • Above white blood cell count is called leukocytosis. It may be due to:

Infectious diseases

  • Inflammatory diseases
  • Leukemia
  • Severe physical or emotional stress

  • Low hemoglobin values ​​may be due to:

Anemia (various types)

  • Blood loss

Factors that may affect blood count results or prevent them from being evaluated:

platelet levels

  • Very high white blood cell count or high triglyceride levels. These can cause falsely elevated hemoglobin levels.
  • Have a lump or mass in the spleen, which can cause a low platelet count or a low white blood cell count. An enlarged spleen can be caused by certain cancers
  • Pregnancy, which usually shows lower values ​​of red blood cells and larger white blood cells.

    Cholesterol is not a health villain. Know Your 9 Functions in Your Body

    Cholesterol is often referred to as being a fat. This is often people's first mistake on the subject. In fact, it is an alcohol with a structure similar to that of a hormone, which behaves like a fat, being insoluble in water and blood. Cholesterol, however, has a film of a compound called lipoprotein, which functions as a kind of coating, making it soluble in water and can be transported through the blood.
