Results with a high or low count are possible.
Low haemoglobin levels might indicate anaemia, iron insufficiency, or thalassemia.
Polycythemia, coronary artery disease and lung disease can all be caused by high haemoglobin levels.
It's worth noting that persons who live at higher elevations have more haemoglobin than those in the lowlands. When analysing test results, it's usually a good idea to see a doctor.
Anything outside of the typical range is seen as abnormal. The typical MCHC range is 33.4–35.5 grams per deciliter (g/dL) in adults.
Disclaimer: It's always good to seek medical advice while evaluating results.
