Patients with hypokalemic Lab-K+ but normal ECG-K+ (false-negative hypokalemia) were less medically complex, presenting with younger age, fewer co-morbidities (DM, HTN, CKD, HF, or proteinuria), lower stress markers (glucose, CRP, pBNP, D-dimer), and higher Alb than those with normal Lab-K+ and ECG-K+. This evidence concerns the gene ALB and chronic kidney disease.
