is a level of 17.50 in ferritin blood test consider low in a male 66 years old
A gold-top tube is typically used to collect blood for serum ferritin testing.
Iron levels in the body are measured by both hemoglobin and serum ferritin blood tests.
Serum ferritin levels are considered the best indicator of iron stores in the body. Ferritin is a protein that stores iron, so measuring its levels in the blood can provide valuable information about the body's iron status.

The tube used for a serum ferritin test is typically a gold or tiger top tube.
Ferritin levels are typically checked using a serum sample collected in a gold or tiger-top serum separator tube. These tubes contain a gel that separates the serum from the blood cells after centrifugation. Some laboratories may also accept light green or dark green tubes, which contain lithium heparin as an anticoagulant. Always check with specific lab protocols, as practices may vary.
The normal levels of serum potassium are 3.5-5.0 mM

To diagnose iron deficiency, a healthcare provider typically orders a complete blood count (CBC) and specific iron studies, which include serum ferritin, serum iron, total iron-binding capacity (TIBC), and transferrin saturation. Low levels of ferritin and serum iron, along with high TIBC, often indicate iron deficiency. Additional tests may be conducted based on the patient's symptoms and medical history.
The normal ferritin level for an adult male typically ranges from about 24 to 336 nanograms per milliliter (ng/mL). However, reference ranges can vary slightly between laboratories. Ferritin levels are an important indicator of the body's iron stores, and levels outside this range may suggest iron deficiency or overload. It's essential to consult with a healthcare professional for interpretation of test results.
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
