4 Reasons to Know the NLR

🩸 An increased NLR positively correlates with higher mortality rates and numerous health conditions such as cardiovascular disease, diabetes, hypertension, pancreatitis, sepsis, bipolar disorder, major depressive disorder, and many others.⁠

🩸 An elevated level is also associated with worse outcomes for several cancers including breast, ovarian, gastroesophageal, pancreas, colon, colorectal, hepatocellular, biliary tract, kidney, and urothelium.⁠

🩸 LabSmarts automatically calculates NLR and plots that value on a color-coded reference range bar graph with an optimal range between 1.5 to 2, supported by the studies found below and in the NLR section of our bibliography.⁠

🩸 LabSmarts also provides possible root causes, conditions, lifestyle, and environmental factors associated with increased and decreased NLR.

Importance of Assessing the Sodium-to-Potassium Ratio (Na/K)

Assessing the sodium-to-potassium (Na/K) ratio offers valuable insights into electrolyte balance and overall health, reflecting the body’s response to stress, inflammation, and adrenal function. By monitoring this key ratio, practitioners can detect early signs of imbalance, guiding more personalized and effective health interventions.
