title: Comparison of lactate, bilirubin and hemoglobin F concentrations obtained by the ABL 700 series blood gas analyzers with laboratory methods.
abstract: OBJECTIVE
  To compare lactate, bilirubin and Hemoglobin F concentrations obtained on ABL 700 series blood gas analyzers with those from laboratory methods.
  
  
  METHODS
  Pooled neonatal plasma, cord blood and adult plasma samples were used for comparison of bilirubin, hemoglobin F and lactate concentrations respectively.
  
  
  RESULTS
  Results obtained on the ABL 700 series compared favorably (Deming regression slopes 0.97-1.13) with those from laboratory methods. For lactate ABL (y) = 1.13 Vitros (x) -0.43 with a CI (slope) of 1.10 to 1.16, CI (int) of -0.61 to -0.28. For hemoglobin F ABL(y) = 1.11 Variant (x) -8.0 with a CI (slope) of 0.88 to 1.33, CI (int) of -25.3 to 9.3. The three bilirubin comparisons are as follows: 1) Unistat (y) = 1.10 Vitros (x) -16.12 with CI (slope) of 1.06 to 1.14 and CI (int) of -25.3 to -6.9. 2), ABL (y) = 0.97 Vitros(x) -10.16 with CI (slope) of 0.94 to 1.00 and CI (int) of -17.6 to 2.73) Unistat (y) = 1.14 (x)-4.58 with CI (slope) of 1.09 to 1.18 and CI (int) of -13.6 to 4.5.
  
  
  CONCLUSIONS
  The ABL 700 series gave comparable results for lactate, bilirubin and hemoglobin F with laboratory methods and may be used in patient care.
