In the US, Eggs Are Refrigerated to Help Reduce Salmonella Risks. If an egg is infected with salmonella, the bacteria will multiply more quickly if the egg is stored at room temperature instead of in the refrigerator, particularly if they're stored for longer than 21 days. This is why, in the US, public health agencies advise keeping your eggs in the fridge.
Whole blood consists of 3 types of blood cells, suspended in a liquid called plasma. Blood circulates through the arteries and veins with each of the blood cell types -- red blood cells, white blood cells and platelets -- performing different functions throughout the body.
1 Red blood cell (RBC) count: is a count of the actual number of red blood cells per volume of blood. 2  Both increases and decreases can point to abnormal conditions. 3  Haemoglobin measures the amount of oxygen-carrying protein in the blood. 4  Haematocrit measures the amount of space red blood cells take up in the blood. White blood cell (WBC) count is a count of the actual number of white blood cells per volume of blood. 2  Both increases and decreases can be significant. 3  White blood cell differential: looks at the types of white blood cells present.
