In the usa, an average gel ferritin quantity are 135 ug/L for males (28), 43 ug/L for females (28), and you can up to 31 ug/L for the children aged 6-a couple of years (23).
Solution metal quantity is a way of measuring the quantity of iron on serum which is have a tendency to provided by results from other routine testing analyzed by automated, research chemistry boards
Serum ferritin concentration are an earlier sign of condition out-of iron stores that will be more particular sign available regarding depleted iron areas, specially when used in conjunction with other assessment to assess iron reputation. For example, certainly one of women that decide to try positive getting anemia on such basis as Hb focus otherwise Hct, a serum ferritin intensity of below or equivalent to fifteen ug/L confirms iron defecit and a solution ferritin concentration of deeper than fifteen ug/L shows that iron insufficiency isn’t the cause for brand new anemia (93). Certainly one of female out-of childbirth many years, the newest sensitiveness of lowest solution ferritin attention (less than otherwise equivalent to 15 ug/L) to possess iron defecit since the laid out from the no stainable bone marrow iron are 75%, while the specificity try 98%; whenever lowest solution ferritin attention is determined on lower than several ug/L, brand new sensitivity to possess iron insufficiency try 61% and also the specificity was one hundred% (93). Even though reasonable serum ferritin focus was a young signal away from lower iron places, it’s been questioned if or not an everyday focus measured when you look at the very first otherwise next trimester of pregnancy can predict enough iron position later in pregnancy (6).
