A normal white blood cell count for any person ranges between 3.5 to 10.5 billion per liter, as reported by Mayo Clinic. A count that falls above or below the normal range requires follow-up with a physician, as it can indicate a serious underlying health issue. A white blood cell count of 3.6 indicates a reading at the low end of the normal range and may require monitoring for further

The normal laboratory reference range for platelets is 150–450 × 109/L. Thrombocytosis is a platelet count greater than 450 × 109/L. Thrombocytopenia is a

The Platelets: ; Normal Platelet level, 150,000 to 450,000 μL, Normal platelet count is different for people depending on age, sex and other factors.

In an adult, a normal count is about 150-400 x 109 per litre of blood. If platelet levels fall below 20 x 109/L, spontaneous bleeding may occur 

11/24 · Platelet count tends to decline with age. A platelet count that is lower than it once was or on the lower end of normal may not be a cause for concern in an older adult —

The upper limit of expected counts (95th percentile) during these peaks were as high as 750,000 microl(-1). Conclusion: The figures herein describe reference ranges for platelet counts and MPV determinations of neonates at various gestational ages during their first 90 days. Expected values differ substantially from the 150,000 microl(-1) to

Normal platelet count range: Between 150,000 and 400,000 platelets per microliter. Low platelet count: Less than 150,000 platelets per microliter. High platelet count: More than 450,000 platelets per microliter. What if I have a low platelet count? Low platelets can prevent blood from clotting. This could be a result of: Bone marrow damage.

Average Platelet Count A normal platelet count is between 150,000 and 400,000 per microliter of blood. Because platelets only live in the body for about 10 days, your bone marrow creates
