A Novel Insight into the Interplay between Serum Uric Acid and Blood Parameters: Unveiling a Complex Relationship
Clinical Laboratory
|June 15, 2026
Summary
Serum uric acid (SUA) is linked to red blood cell count (RBC) and other hematological markers, with non-linear patterns observed. Renal biomarkers like serum creatinine (Scr) partially explain these associations.
Area of Science:
- Clinical Biochemistry
- Hematology
- Nephrology
Background:
- Serum uric acid (SUA) is a key indicator in gout, cardiometabolic, and kidney diseases.
- Relationships between SUA, hematological indices, and inflammatory markers require further population-level characterization, particularly non-linear patterns.
Purpose of the Study:
- To investigate associations between SUA and routine hematological/inflammatory markers in US adults.
- To explore non-linear relationships and the mediating role of renal biomarkers (Scr, BUN) in these associations.
Main Methods:
- Cross-sectional analysis of 12,948 US adults (NHANES 2015-March 2020).
- Examined associations using survey-weighted generalized linear models and restricted cubic splines for non-linearity.
- Mediation analyses explored the role of serum creatinine (Scr) and blood urea nitrogen (BUN).
Main Results:
- Positive associations found between SUA and RBC, WBC, and CRP; no significant association with PLT.
- Non-linear relationships observed: U-shaped for RBC, saturating for WBC and CRP.
- Scr and BUN partially mediated hematological-SUA associations, with complex direct and indirect effects.
Conclusions:
- SUA correlates with hematological and inflammatory markers, notably RBC and non-linear HGB/RDW patterns.
- Renal biomarkers (Scr, BUN) partially explain these links, suggesting integrated risk assessment.
- Further longitudinal studies are needed to confirm causality.

Serum Studies: Renal Function Tests
Renal function tests are crucial for assessing kidney health, monitoring disease progression, and evaluating the kidneys' efficiency in waste elimination, fluid balance, and electrolyte regulation. These tests offer critical insights into kidney function, even though routine measurements may appear normal until there is a significant decline in the glomerular filtration rate or GFR. Typically, signs of kidney impairment only become evident when the GFR falls to about 50% of its normal level.
Renal Regulation of Acid-Base Balance
Metabolic reactions in the body produce nonvolatile acids, such as sulfuric acid, which generate an acid load of approximately 1 mEq of H+ per kilogram of body weight daily. Excreting H+ in the urine is essential to balance this acid load.
In the kidneys, cells within the proximal convoluted tubules (PCT) and the collecting ducts secrete hydrogen ions (H+) into the tubular fluid. Specifically, in the PCT, Na+/H+ antiporters secrete H+ while reabsorbing Na+.

Drug Dosing in Renal Diseases: Measurement of Glomerular Filtration Rate
The glomerular filtration rate (GFR) is a critical indicator of kidney health, reflecting how well the kidneys filter blood. Changes in GFR can signal potential kidney impairment, necessitating accurate measurement methods to monitor kidney function effectively.Various molecules can serve as markers for GFR measurement, with the ideal marker meeting several specific criteria. It must freely filter at the glomerulus, avoid reabsorption or secretion by the renal tubules, remain unmetabolized, not...
Urine Studies I: Urinalysis
Urinalysis is a widely used diagnostic test that analyzes urine's physical, chemical, and microscopic characteristics. Healthcare providers use it to detect and monitor various health conditions, including renal disease, urinary tract infections (UTIs), diabetes, and metabolic or systemic disorders.Components of UrinalysisUrinalysis consists of three primary components: physical, chemical, and microscopic examination. Each provides unique insights into the urine sample and, by extension, the...
Blood Studies for Cardiovascular System III: Serum Lipid Profile
Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...
