The normal white blood cell range is 4,500-10,000 white blood cells per micro liter. Low white blood cell count is considered to be anything under 4,500 per micro liter.
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.
.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.

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).

250 ml
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.
1 mL blood = 1.06 g
