Plasma ammonia and glucose concentrations were normal, but urinary excretion of malate, fumarate and other tricarboxylic acid cycle intermediates was increased.
Furthermore, plasma ammonia positively correlated with blood THC concentrations (P=0.03).
Plasma ammonia measurement is greatly influenced by pre-analytical conditions, which may lead to false positives.
There are seven different platforms measuring plasma ammonia within this vast clinical catchment area.
Lastly, a new concept of a two-step non-thermal plasma ammonia synthesis method was also proposed.
We wanted to evaluate the prevalence and clinical impact of plasma ammonia false positives in a pediatric population.
No significant differences in maternal and neonatal demographics, nutrient intake, plasma ammonia and total and essential amino acid concentrations were present between the two groups.
Nutrient intake, plasma ammonia, arginine, and amino acid concentrations were measured in all infants at days 3, 14, and 28 and at the time of diagnosis of NEC.
Care of children with metabolic disorders in these remote areas is assisted from Adelaide, and at times, using plasma ammonia results from laboratories up to 3000 km away.
Hence, a correlation study was conducted to examine the relationship between plasma ammonia results from the seven different platforms in use throughout central Australia.
At 30 min, we found marked increase in striatal ammonia (P<0.0001) associated with significant increase in plasma ammonia (P=0.042) concentration.
