This study presents a rapid spectrophotometric method to estimate fetal hemoglobin (HbF) levels. This allows for accurate correction of carboxyhemoglobin (HbCO) and oxygen saturation (SO2) measurements in human blood.

Area of Science:

  • Clinical chemistry
  • Hematology
  • Analytical chemistry

Background:

  • CO-oximetry is crucial for measuring carboxyhemoglobin (HbCO) and oxygen saturation (SO2).
  • Fetal hemoglobin (HbF) can introduce systematic errors in these measurements.
  • Accurate HbF quantification is clinically significant for precise HbCO and SO2 interpretation.

Purpose of the Study:

  • To develop a simple and rapid method for estimating fetal hemoglobin (HbF) in human blood.
  • To enable correction of carboxyhemoglobin (HbCO) and oxygen saturation (SO2) measurements affected by HbF.
  • To provide a time-efficient alternative to conventional HbF analysis methods.

Main Methods:

  • Utilizes spectrophotometric measurements with a CO-oximeter.
  • Involves two distinct measurements of oxy- and carboxyhemoglobin from the same blood sample.

  • Includes a deoxygenation procedure to facilitate HbF estimation.

    • Main Results:

    • The method allows for the estimation of fetal hemoglobin (HbF) percentage.
    • Enables the correction of systematic errors in HbCO and SO2 values caused by HbF.
    • The entire procedure, including deoxygenation, is completed in approximately 40 minutes.

    Conclusions:

    • The described spectrophotometric method offers a fast and straightforward approach for HbF estimation.
    • This technique improves the accuracy of carboxyhemoglobin and oxygen saturation measurements.
    • It serves as a clinically valuable and time-saving alternative to traditional methods like HPLC or electrophoresis.
