The pH and blood gas values of umbilical blood samples must be determined as soon as possible after birth to avoid changes in pH, oxygen pressure (PO 2 ) and carbon dioxide pressure (PCO 2 ). Since a continuous around‐the‐clock laboratory service is not available in every hospital, a method of reducing these changes is desirable. Determination of pH and blood gas values at different time intervals while the samples were stored on ice showed that pH decreased by a mean of 0.003 unit/hr, whereas PCO 2 and PO 2 increased. A method of reducing glycolysis in blood cells must be found to make postponement of analysis acceptable.
