The definitive test would be obtaining either CO-oximeter or a methemoglobin level on an arterial blood gas test. [3] Arterial blood with an elevated methemoglobin level has a characteristic chocolate-brown color as compared to normal bright red oxygen-containing arterial blood; the color can be compared with reference charts.

Hgb - the infant's hemoglobin should be tested from cord blood. [5] Reticulocyte count - Reticulocytes are elevated when the infant is producing more blood to combat anemia. [5] A rise in the reticulocyte count can mean that an infant may not need additional transfusions. [18]
[3] [10] Blood lead levels 50 to 1,000 times higher than preindustrial levels are commonly measured in contemporary human populations around the world. [3] The National Academies evaluated this issue [ 12 ] in 1991 and confirmed that the blood lead level of the average person in the US was 300 to 500 times higher than that of pre-industrial humans.
Newborn infant with Rhesus disease, a type of hemolytic disease of the newborn, suffering from hydrops fetalis (edema caused by heart failure). The infant did not survive. [4] Signs of hemolytic disease of the newborn include a positive direct Coombs test (also called direct agglutination test), elevated cord bilirubin levels, and hemolytic anemia.
[81] [82] Blood lead levels below 10 μg/dL have been reported to be associated with lower IQ and behavior problems such as aggression, in proportion with blood lead levels. [21] Between the blood lead levels of 5 and 35 μg/dL, an IQ decrease of 2–4 points for each μg/dL increase is reported in children. [ 42 ]
ICD-10 is the 10th revision of the International Classification of Diseases (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. [1]
Elevated alpha-fetoprotein refers to a state where alpha-fetoprotein levels are outside of the reference range. There are two categories of AFP tests: tests performed on serum (blood plasma), and tests performed on amniotic fluid. Tests performed on serum are further categorized by the reason for performing the test: maternal serum, adult tumor ...
The volume of blood removed was calculated by subtracting the weight of the empty collection container from that of the container filled with blood. They found that the mean volume of blood drawn for the 578 tests exceeded that requested by the hospital laboratory by 19.0% ± 1.8% per test.
