Normal values of white blood cells are 4500-10,000 in adults. In the elderly, total WBC will decrease slightly. In response to acute infection, trauma or inflammation, the number of WBCs increases and in some diseases, such as sepsis, the increase in WBC is so dramatic that resembles leukemia (leukemoid reaction).
The study included 207 men and 220 women comprising 69% of the invited 75-year-olds in a defined geographical area. Main Results. The median WBC count (in 10(9)/L) was 6.3 (interquartile range 5.4-7.2) for men and 5.7 (4.9-6.8) for women, P < 0.001 for sex difference.
The normal range for WBC is 5 to 10 K/uL. Your CBC will also measure what’s called the ANC (absolute neutrophil count) That’s the specific number of white blood cells in your blood that fight infection.
In general, for adults a count of more than 11,000 white blood cells (leukocytes) in a microliter of blood is considered a high white blood cell count.
A: For an adult, a healthy WBC count is considered to be between 4,000 and 11,000 WBCs per microliter of blood. This is on average – some healthy individuals may have a higher or lower count.
The normal range for your WBC is usually 4,500 to 11,000 cells per microliter. Your WBC is generally considered high if it is greater than 11,000 cells per microliter. Once you have your test results, your doctor will work with you to create the appropriate treatment plan, if necessary.
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.
The specific number for high 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.
White blood cells (WBCs): WBCs help you fight infections, so a high WBC count could be an indication that you have an infection or some type of inflammation. A normal WBC range is between 4,300 and 10,800 cmm.
Normal white blood cell counts are: 9,000 to 30,000/mm3 for newborns. 6,200 to 17,000/mm3 for children under 2 years old. 5,000 to 10,000/mm3 for children older than age 2 and adults.
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.
Causes of an elevated white blood cell count include infection, abnormalities in the bone marrow, smoking, chronic lung disease, immune disorders, inflammatory or allergic reactions or even physical and emotional stress.
A low white blood cell count in adults is less than 4,000 cells per microliter of blood. A low white blood cell count can be an indicator of certain conditions, including lupus, rheumatoid arthritis, vitamin deficiencies, or a side effect of cancer treatment.
White blood cell count varies from person to person. The normal range is usually between 4,000 and 11,000 white blood cells per microlitre of blood. Anything below 4,000 is typically considered to be a low white blood cell count.
In general, for adults a count lower than 4,000 white blood cells per microliter of blood is considered a low white blood cell count.
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.
