Thus, in term neonates, a FE Na of <3% represents volume depletion, and a FE Na as high as 4% may represent maximal sodium conservation in critically ill preterm neonates. [4] [5] The FE Na may also be spuriously elevated in children with adrenal insufficiency or pre-existing kidney disease (such as obstructive uropathy) due to salt wasting. [6]
Arterial levels for drugs are generally higher than venous levels because of extraction while passing through tissues. ... Children 2-16 y: 0.1 [87] 0.6 [87] ng/dL ...
Iron-deficiency anemia is anemia caused by a lack of iron. [3] Anemia is defined as a decrease in the number of red blood cells or the amount of hemoglobin in the blood.

[8] [9] [10] To date, the results in both adults and children have been modest and this technique can not be universally recommended. [11] [12] It has also been noted that factors other than inflammation can increase eNO levels, for example airway acidity. [13] [14]
The normal range of GFR, adjusted for body surface area, is 100–130 average 125 (mL/min)/(1.73 m 2) in men and 90–120 (mL/min)/(1.73 m 2) in women younger than the age of 40. In children, GFR measured by inulin clearance is 110 (mL/min)/(1.73 m 2 ) until 2 years of age in both sexes, and then it progressively decreases.
Apples. The original source of sweetness for many of the early settlers in the United States, the sugar from an apple comes with a healthy dose of fiber.
