These cells are vital for protecting your body against infections, foreign invaders, and inflammation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The five primary types of white blood cells are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Neutrophils<\/strong> \u2013 Fight bacterial infections.<br><\/li>\n\n\n\n<li><strong>Lymphocytes<\/strong> \u2013 Protect against viruses and maintain immune memory.<br><\/li>\n\n\n\n<li><strong>Monocytes<\/strong> \u2013 Remove dead or damaged cells.<br><\/li>\n\n\n\n<li><strong>Eosinophils<\/strong> \u2013 Help fight parasitic infections and are actively involved in allergic reactions.<br><\/li>\n\n\n\n<li><strong>Basophils<\/strong> \u2013 Trigger allergic responses.<br><\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Normal WBC (TLC) Range &amp; Variations<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The normal WBC range for adults usually falls between 4,000 and 11,000 cells\/\u00b5L (4.0\u201311.0 \u00d7 10\u2079\/L). However, factors such as pregnancy, stress, smoking, or vigorous exercise can temporarily influence this range. Slight deviations may not always signal disease, but consistent elevations need evaluation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>When Is TLC High? Severity Levels<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A TLC above <strong>11,000 cells\/\u00b5L<\/strong> is generally considered high (leukocytosis).
