The Effect of the Patient's Acid-Base Balance on Azostix Strips' Estimation of Blood Urea

“…The difference between blood above figures give a reasonable picture of the spread and plasma urea concentrations has been estimated of concentrations which the chart readings represent. by various workers as 3 mg/l00 ml (Keyser and Using these values, the AutoAnalyzer results were Waters, 1968), IG-15 mg/l00 ml (Jordan and then transposed into notional Azostix readings, Austin, 1968), 7% (Sacre and Walker, 1968), 15% that is, the readings which would be obtained from above list, in the range of the 45-85 reading on Azostix, and therefore this is the notional Azostix reading for this blood specimen. If the actual Azostix reading were 85, the difference of the actual from the notional reading would be + l colour block; if the actual reading were 20-45, the difference would be -I colour block.…”
