Urea is transported to the kidneys for excretion. A normal range for blood urea nitrogen is generally 8 to 24 mg/dl for adult males and 6 to 21 mg/dl for females. Generally, a high blood urea nitrogen level means that the kidneys are not performing well, particularly if the result is above 50mg/dl.
The amount of circulating iron bound to transferrin is reflected by the serum iron level. The serum iron reference range is 55â160 Âµg/dL in men and40â155 Âµg/dL in women.erum iron levels are often low in untreated iron deficiency anemia; however, levels may be normal. If patients with iron deficiency anemia receive iron medication before blood is drawn, normal or high concentrations are typically noted.
