what is the difference between whole blood and peripheral blood?
11934
Peripheral blood or whole blood carries the various blood cells, i.e., erythrocytes (red blood cells), leukocytes (white blood cells), and thrombocytes (platelets), suspended in blood plasma. Plasma consists mostly of water, but also contains proteins, glucose, ions, hormones, and clotting factors.

They contain hemoglobin, a red pigment that is able to transport oxygen as oxyhemoglobin to all parts of the body. Red blood cells make up about 45% of the blood. Plasma, is the liquid component of the blood. ... Dissolved nutrients are found in plasma as are wastes such as carbon dioxide, urea and lactic acid.

The mean platelet count blood test is typically part of a complete blood count (CBC) test. A CBC reveals important information about the number of different blood cells in the body. Platelets, also called thrombocytes, are fragments of larger cells made in the bone marrow called megakaryocytes.

Hematocrit will be higher in most venous blood than in the corresponding arterial blood since fluid passes out of the vascular space and thence to lymphatic channels. The same number of red cells in less fluid means the haematocrit will be higher. ... Since it's a fraction, there are two ways to have a higher hematocrit.

Understanding the WBC (white blood cell) count A white blood cell (WBC) count is a test that measures the number of white blood cells in your body. This test is often included with a complete blood count (CBC).

Your blood is made up of liquid and solids. The liquid part, called plasma, is made of water, salts, and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells, and platelets.

A key difference between plasma and serum is that plasma is liquid, and serum is fluid. While most of the components are the same for both plasma and serum, plasma contains fibrinogen which is absent in serum.

Red blood cells transport oxygen to your body's organs and tissues. White blood cells help your body fight infections.

Whole blood and serum blood glucose is often different. Red blood cells have higher concentration of protein than serum and serum has higher water content and more dissolved glucose than whole blood. To obtain blood glucose in serum from figures in whole blood, it is multiplied by 1.15.

A complete blood count (CBC) is a blood test used to evaluate your overall health and detect a wide range of disorders, including anemia, infection and leukemia. A complete blood count test measures several components and features of your blood, including: Red blood cells, which carry oxygen.

The cellular portion of blood contains red blood cells (RBCs), white blood cells (WBCs) and platelets. The RBCs carry oxygen from the lungs. The WBCs help to fight infection, and platelets are parts of cells that the body uses for clotting. All blood cells are produced in the bone marrow.

The full blood examination, also called FBE or FBC, measures the numbers and size of the important cells types in the blood as well as the blood haemoglobin level. Haemoglobin is the protein in red blood cells that gives blood its red colour.

Red blood cells carry oxygen around the body for respiration to take place while white blood cells defend the body from infections and viruses. In terms of structure: 1. Red blood cell has a biconcave shape while white blood cell is irregularly shaped.

A red blood cell (RBC) count is a blood test that tells you how many red blood cells you have. Red blood cells contain a substance called haemoglobin, which transports oxygen around the body.

The differences between capillary and venous blood in most cases are minimal. However, there are some discrepancies in hemoglobin and hematocrit values and in platelet counts. It is well known that capillary blood has higher hemoglobin and hematocrit values than venous blood.

If blood is drawn into a tube without anticoagulant: plain red or SST, then the blood will clot naturally and separate into liquid and cells. This liquid is called serum. ... Blood outside the body with anticoagulant is referred to as whole blood. Whole blood can still be separated into liquid and cells.
