These vary a bit depending on the lab, so the ranges that follow are guidelines rather than absolutes. Be sure to ask for a copy of the CBC each time it’s performed, and look at the lab results sheet for the normal range for that lab. Still, there are some general rules of thumb:
Red blood cells (RBC)Normal for men: 4.5 to 6.2 million per microliter (a single drop). Normal for women: 4.2 to 5.4 million per microliter.
White blood cellsNormal for men and women: 3,700 to 10,000 per microliter. Lowest level at which someone is safe from infection: 1,000.
PlateletsNormal range for men and women: 150,000 to 450,000 per microliterLowest level at which someone’s blood can still clot normally: 100,000. Level at which there’s a risk of spontaneous bleeding: 50,000. Level at which bleeding can become life-threatening: 5,000.
