Results Hyperventilation and low serum bicarbonate concentrations were associated with urine pH above 5.5 and positive urine anion gap in all, suggesting CRA. The diagnosis was later confirmed by obtaining capillary blood gas, which showed a decrease in PCO 2 and high normal pH values. Conclusion ...
In addition, the urine anion gap (Na + K - Cl) was 103 meq/L in the absence of renal disease. This indicated that the expected large quantity of urinary ammonium must have been masked by an even greater quantity of unmeasured anion; in this case proven by direct measurement to be B-...
Urine osmolal gap was lower ( P < 0.05) in the dRTA patients (129.7 ± 17.0 mmol/L) than in the NCs (319.7 ± 58.4 mmol/L). When the data from all subjects were pooled, urine anion gap correlated inversely with urine NH 4 + ( r = 0.70, P < 0.001) and with NAE ( r = ...
Define urine pH. urine pH synonyms, urine pH pronunciation, urine pH translation, English dictionary definition of urine pH. n. The waste product secreted by the kidneys that in mammals is a yellow to amber-colored, slightly acidic fluid discharged from
Urine anion gap was higher (P < 0.001) in the CRF (24.7 ± 2.2 mmol/L) and dRTA (36.7 ± 7.7 mmol/L) patients than in the NCs (−16.2 ± 5.5 mmol/L). Urine osmolal gap was lower (P < 0.05) in the dRTA patients (129.7 ± 17.0 mmol/L) than in the NCs (319.7 ± 58.4 ...
The urine anion gap: a clinically useful index of ammonium excretion. In patients with a normal plasma anion gap type of metabolic acidosis, knowledge of the rate of ammonium excretion can provide valuable information to dete... MB Goldstein,R Bear,RMA Richardson,... - 《American Journal of ...
Although not statistically significant after multiple testing correction, these results are likely to contain true positive findings based on biological plausibility and previous studies, such as the association of ALPL with phosphate-containing metabolites (minimum p = 2.3e−9)24, DPYD and ...
setting, the urine net charge is positive and underestimates ammonium excretion because the cations—ammonium, sodium, and potassium—are excreted with the unmeasured anion instead of chloride. In infants, the validity of the urine net charge is also compromised due to considerable variability in ...
Method: cAMP and 13C5-cAMP internal standard were extracted from EDTA plasma using a weak anion exchange solid phase extraction. Chromatography was performed in positive electrospray ionisation mode, using a pentafluorophenyl column with a 10 mins 2% formic acid water:acetonitrile gradient. Transitions ...
In a metabolic acidosis without a serum anion gap: A positive urine AG suggests a low urinary NH₄⁺ (renal tubular acidosis). A negative urine AG suggests a high urinary NH₄⁺ (diarrhea). FAQs How do I calculate urine anion gap? To calculate the urine anion gap: Measure the ...
