According to reputable medical sources, a normal adult serum iron range is typically 60-170 mcg/dL, placing a reading of 70 mcg/dL within this healthy window. The question 'is 70 iron good' therefore receives a positive initial answer, but this single metric provides only part of a complex picture regarding your body's overall iron status.

According to typical reference ranges, a serum iron level of 200 mcg/dL significantly exceeds the upper limit for most adults, though a 200 ferritin reading requires more context. Therefore, determining if 200 iron is high depends on the specific blood test performed and a broader analysis of your overall health.

According to the National Institutes of Health, the amount of iron in your blood can vary throughout the day. So, do iron levels fluctuate daily? Yes, they do, largely influenced by your body's internal clock, or circadian rhythm, and other factors, making the time of day a critical consideration for blood tests.

According to a study published on bioRxiv, serum iron levels are regulated by the body's endogenous circadian clock, with concentrations typically higher during the day and lower at night. This established scientific fact directly answers the question, **does iron fluctuate daily?**, and highlights why the timing of blood tests is so crucial.

Clinical guidelines often suggest stopping iron supplements at least 24 to 48 hours before an iron-related blood test to ensure accurate readings. Knowing exactly how long to not take iron supplements before a blood test is crucial to avoid false results, which can impact your diagnosis and treatment plan. This guide explains why preparation is key for reliable lab work.

According to the World Health Organization, iron deficiency is the most common nutritional deficiency worldwide. It's not something you can count yourself at home, but rather a process managed by healthcare professionals using a suite of blood tests that precisely measure your body's iron status.

According to studies on acute iron poisoning, a serum iron level of 1000 µg/dL or higher is associated with fatal outcomes. However, a precise answer to **what iron level is considered life threatening?** depends on various factors, including the clinical context and the patient's individual response.

Blood test results can be confusing, as a single number like 102 is meaningless without knowing the specific test, its units, and the lab's reference range. Understanding whether a value of 102 signifies a healthy iron status or a deficiency requires a complete iron panel interpretation from a healthcare provider.
