I have a child with a rare urea cycle disorder called ornithine
transcarbamylase deficiency.  In this disorder, the capacity to
eliminate ammonia (a by product of protein, among other sources) is
impaired, necessitating a low protein diet and medicine designed to
remove ammonia.  Glutamine absorbs ammonia, and high glutamine levels
generally indicate that the body's buffer to ammonia absorbtion are
reaching limits.  However, my child is exhibiting very low ammonia
levels combined with very high glutamime levels.  What does this mean?
 Gernally high glutamine and high ammonia go hand in hand.
