<unk> s can be used in the diagnosis of a number of acidosis conditions such as lactic, metabolic, and respiratory acidosis, diabetic ketoacidosis, and also of respiratory alkalosis. Particularly, umbilical cord blood<unk>  analysis can give an indication of preceding fetal hypoxic stress. In combination with other clinical information, normal paired arterial and venous cord blood<unk>  results can usually provide a robust defence against a suggestion that an infant had an intrapartum hypoxic‐ischaemic event. Abnormal results may be due to a wide range of diseases, including poisoning and trauma as well as lung, kidney, or metabolic diseases. Drug overdose and uncontrolled diabetes may be determined from abnormal results. Head or neck injuries or other injuries that affect breathing can also lead to abnormal results.
