What is a dangerously high WBC count?
A normal white blood cell count is generally about 4,500 to 11,000/μL. White blood cell counts that are too high or too low may be dangerous, depending on the cause. A high white blood cell count is called leukocytosis, which is generally diagnosed when white blood cell levels exceed 11,000/μL.What is critical blood value?

Adult white cell counts range from 4,000 to 10,000. So your value of 12,000 is slightly elevated. But as with all medical tests, a small percentage of people will have results that are slightly out of the normal range even though nothing is wrong.Is a WBC of 9 high?
Normal Results The normal number of WBCs in the blood is 4,500 to 11,000 WBCs per microliter (4.5 to 11.0 × 109/L). Normal value ranges may vary slightly among different labs. Some labs use different measurements or may test different specimens.

Median critical values are as follows: PT, more than 37 seconds; INR, more than 5; aPTT, more than 100 seconds; and fibrinogen level, less than 100 mg/dL. These critical values are clinically relevant because they indicate an elevated bleeding risk from excessive anticoagulation or factor deficiency.
What does a WBC of 23000 mean?
The specific number for high (above normal) white blood cell count varies from one lab testing facility to another, but a general rule of thumb is that a count of more than 10,500 leukocytes in a microliter of blood in adults is generally considered to be high, while 4,500-10,500 is considered within the normal range.
What if WBC count is more than 17000?
Having white blood cell levels above this range can be a sign of leukocytosis. If you have WBC counts between 50,000 and 100,000 per microliter of blood, it may mean that you have a severe infection, organ rejection, or a solid tumor.

Is leukopenia life threatening?
Because leukopenia involves low levels of infection-fighting immune cells, it can cause some potentially serious complications if left untreated. Some of the complications of leukopenia include: needing to delay cancer treatment because of a mild infection.
How can you improve low white blood cell count?
While no specific foods or diet changes are proven to increase production of white blood cells, if you have low WBC (leukopenia), it is very important to practice good hygiene, hand-washing, and food safety practices. Neutrophils are the cells that fight bacterial infection.
What is the most common reason for low white blood cell count?
A low white blood cell count usually is caused by: Viral infections that temporarily disrupt the work of bone marrow. Certain disorders present at birth (congenital) that involve diminished bone marrow function. Cancer or other diseases that damage bone marrow.
Can you have leukemia with low WBC?
People with CLL may also have a high or low white blood cell count. Because their bone marrow is producing too many abnormal white blood cells, they don’t have enough normal cells. As a result, they may experience frequent infections that don’t go away on their own.
Should I worry about low neutrophils?
Lower neutrophil levels can cause dangerous infections. These infections can be life threatening when they’re untreated. Having severe congenital neutropenia increases your risk for other conditions.
