Whenever in consonance with the National Institutes of Health, very simple blood test can easily determine whether a patient’s WBC count falls within the normal range of 4500 to 10000 cells per microliter of blood. While those with readings above 10000 had the highest death rate, patients who had WBC counts between 3500 and 6000 cells per microliter of blood had the lowest observed rate of death. Overall, whitish blood cell counts fell for both men and women over the nearly 45year study period.
Host of societal and lifestyle changes could explain the drop, the researchers said, including improvements in diet and exercise habits and the steady drop in smoking and drinking. Environmental changes, like improved sanitary conditions and less frequent exposure to infectious agents, could also be factors. One expert said it’s on the basis of the findings. Participants were healthy at the time of their entry into the study. WBC counts, body mass indexes, and cholesterol and blood pressure levels were tallied during biannual medical evaluations. It’s a well-known fact that the findings are published in the May 8 the Journal issue of the American College of Cardiology.
Death because of cardiovascular disease, especially, rose together with increasing WBC counts. Anyways, WBC counts showed little connection to deaths by cancer. Actually the finding applied to all patients regardless of their initial baseline WBC count, and held regardless of gender, age at death, or year of death. Women tended to have significantly lower WBC levels than men. Seriously. No firm conclusions were drawn regarding the risk for patients with WBC levels below 3500. Illness or invasion by a foreign body typically provokes a rise in almost white blood cells, while a below normal WBC count may indicate bone marrow failure and also liver and spleen disease.
Physical or emotional stress and certain chronic medications can also prompt an increase. Analysis of death records revealed that those participants who died throughout the study period had higher WBC counts than those who survived through to 2002. Basically the death rate for Americans has also fallen steadily over the past four decades, the authors noted. They stressed that they can not establish any causal link between declines in whitish blood cell counts and improving life expectancy. Notice, the authors observed that death risk varied even within the normal WBC count range. I’m sure you heard about this. Those with a high normal WBC count of 6000 to 10000 had a 30 percent to 40 percent higher risk of death than patients with a low normal WBC count of 3500 to 6000, the researchers said. In their study, Ruggiero and colleagues examined data collected during a multi decade study on aging. They tracked the medical histories of more than 2800 men and women from the Baltimore and Washington. Although, either, people with normal whit cell counts may not be out of danger the team of Italian and American researchers said.
