4.4-11.3 White Blood Cells/mm3
The average adult has between 4,000 to 11,000 white blood cells per microliter of blood. The total number of white blood cells in the body can vary depending on individual factors such as age, health status, and stress levels.
White blood cells are the largest of the blood cells but also the fewest. There are only 5000 to 10,000 white blood cells per microliter. There are several different types of white cells but all are related to immunity and fighting infection. On average there are 50 microliters in one drop of blood. There are 250,000 to 500,000 white blood cells per drop of blood.
The number of red blood cells in a ml of "horse's" blood varies with training, exertion and age. 6-8 million per ml with some high and low variation.
White blood cells are a vital part of the immune system and play a key role in fighting infections and diseases. They work by detecting and destroying pathogens such as bacteria, viruses, and other harmful substances in the body.
.gateway.net.au/~mcvc/horses/red.html Packed Cell Volume: This is mostly the percentage of cells within the blood. The red cells have the larger percentage as there are usually 6-8 million/ml as against white cells of 6-8 thousand/ml. PCV is used to assess dehydration and anaemia. Optimum levels are close to 40% with levels below 35% and above 45% likely to indicate problems. This reading is also affected by excitement at collection. PCV also rises as fitness increases, often though, it keeps rising when problems occur because dehydration is a common sequel of work-related problems.

The formula to calculate red blood cells is: Total Red Blood Cells (RBC) = Red blood cell count (RBC count) in millions per microliter (mcL) x Volume of blood in milliliters (mL).
250 ml
A normal healthy person has about 6 liters of blood and makes 25 -30 ml every day so would make a complete new pool of blood ever 200 or so days. You can make the blood faster if needed. Within the "blood" total the red blood cells last about 120 days, platelets about a week and white blood cells a few hours to days for the most common types (but years for some types).
A normal red blood cell count is about 5,000,000 per uL. There are 1,000 uL per ml and 5 ml per tsp so: 5x10^6 x 10^3 x5 = 25x10^9 or 25,000,000,000 or 25 trillion.
Typically when people refer to a blood bag they mean a transfusion of packed red blood cells. A transfusion of one unit of packed red blood cells would be approximately 250 mL.
