nitrogen balance see nitrogen balance.
positive balance a state in which the amount of water or an electrolyte excreted from the body is less than that ingested.

acid-base balance
the proportion of acid and base required to keep the blood and body fluids neutral. See also acid-base balance.

balance examination
simultaneous palpation of muscles on both sides of the body of Greyhounds attempting to locate areas of soreness or spasm.
fluid balance
the state of the body in relation to ingestion and excretion of water and electrolytes (see also fluid balance).
nitrogen balance
the state of the body in regard to ingestion and excretion of nitrogen. In negative nitrogen balance the amount of nitrogen excreted is greater than the quantity ingested. In positive nitrogen balance the amount excreted is smaller than the amount ingested. See also nitrogen balance.
posture balance
