The normal level of ferritin varies between men and women: The lower the ferritin level, even within the "normal" range, the more likely it is that the patient does not have enough iron. Once the level dips below this range they are classified as being anemic and should see a hemotologist and a gastroenterologist for additional diagnostic tests and treatment. Normal ferritin levels follow: Male: 12-300 ng/mL Female: 12-150 ng/mL Note: ng/ml = nanograms per milliliter http://www.nlm.nih.gov/medlineplus/ency/article/003490.htm
Ferritin level tells the amount of iron in your blood. Ferritin is stored in red blood cells, so I guess you could call it "backup iron." Male: 12-300 ng/mL Female: 12-150 ng/mL That's a big range, so your physician may want to supplement your iron even though it's within the normal range.
is a level of 17.50 in ferritin blood test consider low in a male 66 years old
The normal range of ferritin in children increases as they age. In children between the ages of 1 and 5 years, the normal range is 6 to 24 ng/mL. In children between 5 and 9 years of age, the normal range increases to 10 to 55 ng/mL. These levels continue to increase into adulthood, at which point they can be up to 200 ng/mL.
It depends what unit of measurement you're using. According to the Wikipedia article on Ferritin - normal levels are "...usually between 30-300 ng/mL (=μg/L) for males, and 15-200 ng/mL (=μg/L) for females..." - See related link for a full article on the substance.
4.0 to 8.0 ng/ml
2 ng/mL produces a positive drug test result.
1 nanogram (ng) = 0.001 microgram (ug). 1 milliliter (mL) = 0.01 deciliter (dL) (ng / mL) * (ug / ng) * (mL / dL) = ug / dL Therefore, 1 ng / mL = (1 ng / mL) * (0.001 ug / ng) * (mL / 0.01 dL) = 0.1 ug / dL
You *definitely* need to follow up with an MD, even if you feel fine. According to WebMD, "Very high ferritin levels (greater than 1,000 ng/mL) can mean a large buildup of iron in the body (hemochromatosis)." Its a common genetic disorder than can greatly increase the risk of a whole host of serious diseases if not treated. My niece's husband received treatments for this. DO NOT try to self-treat with supplements.
t3 0.60-1.81 ng/ml t4 5.01-12.45 ug/ml tsh 0.35-5.50 uiu/ml these are normal thyroid levels.
Cotinine levels <10 ng/mL are considered to be consistent with no active smoking. Values of 10 ng/mL to 100 ng/mL are associated with light smoking or moderate passive exposure, and levels above 300 ng/mL are seen in heavy smokers - more than 20 cigarettes a day. In urine, values between 11 ng/mL and 30 ng/mL may be associated with light smoking or passive exposure, and levels in active smokers typically reach 500 ng/mL or more.
In the military it's 100 ng/ml. Anything less won't come back as positive on a Urinalysis
