It is calculated by dividing number of neutrophils by number of lymphocytes. Neutrophil-Lymph ocyte Ratio (NLR): a relatively new measure/ratio thought to indicate the level of subclinical or overt inflammation. Poorer outcomes: in patients with certain cancers, COPD.Cardiovascular risk: this association has been shown in the general population and in rheumatoid arthritis patients that higher RDW are associated with MI, CVE events, metabolic syndrome and cardiovascular events.Thrombosis: RDW is high in patients with MI, deep vein thrombosis and pulmonary embolism.Inflammation: RDW has been shown to rise with inflammation in multiple disorders. Higher RDW values have been seen in RA, lupus, adult-onset Still’s patients (AOSD), etc. The relationship between RDW and CRP or other proinflammatory cytokines is unclear.
But did you know that the RDW may also be increased with inflammation: The RDW is increased in iron deficiency and macrocytic anemias. RDW (red cell distribution width): is a measure of anisocytosis (variation in RBC size). And while there are other reactants (SAA, haptoglobin, complement levels) that can be measured, one need not look beyond the CBC for supplementary inflammatory evidence, as the consequences of inflammation includes: anemia of chronic disease, leukocytosis and thrombocytosis. I’ve compiled several CBC “pearls” and their interpretation below:ĬBC and Inflammation: while many rely on the acute phase reactants (C-reactive protein, erythrocyte sedimentation (ESR) to assess or identify inflammation, rheumatologists learn early that nearly half of patients with obvious inflammation will have normal ESR and CRP values. Numerous studies have reinforce old lessons and revealed new clues and clinical associations and to be gleaned from the CBC report. After years of training, practice and patient care, the CBC continues to inform and guide.īeyond the marquee numbers (WBC, hemoglobin, hematocrit, platelets), the CBC report comes with a supportive cast of numbers (e.g., MCV, MCHC, RDW, MPV), cell subsets and morphologies that shed light and point the way.

The CBC result can spark the diagnosis of infection, leukemia, ITP and Still’s disease. A measure of the vital cells that circulate, sustain and protect life, the CBC has become the (albeit mundane) pivotal gauge of wellness, drug safety or disease activity.Įarly in training, each of us is taught to look to the CBC for critical information. It's easily obtained, cheap and chock full of clues, news and reasons to act, worry, test or not. CBC…it’s easy as 123! The complete blood count (aka, CBC) is the most routine, but indispensable, of all medical assessments.
