The iron that is part of hemoglobin is directly involved in the transport of oxygen through the tissues of the body. Deficiency, as well as the increased content of this microelement, negatively affects many functions of organ systems. A person experiences fatigue, weakness, drowsiness. With such symptoms, a blood test for iron is prescribed.
Indications for a blood test for iron
A high or low level of iron in the blood affects the appearance and well-being of the patient. Trace deficiency is manifested by pallor, loss of strength. Elevated levels of iron (ferrum) are reflected in joint pain, bleeding and malaise. The main indications for a blood test for iron are:
- suspicion of poisoning with iron substances.
- the need to adjust the daily diet;
- suspicion of impaired blood formation;
- diagnosis and differentiation of different types of anemia;
- the presence of chronic liver diseases (hepatitis, cholecystitis, hepatopathies);
- detection of infectious pathologies of any form;
- bleeding of various etiologies;
- suspicion of hemochromatosis (hereditary pathology in which iron metabolism is impaired);
- suspected lack of vitamins;
- the presence of pathologies of the gastrointestinal tract;
- the need to determine the level of effectiveness of the therapy.
To obtain accurate results of the study, analysis must be prepared in advance. Please note that blood for ferrum control must be donated to an empty stomach, preferably before 10 in the morning (while the maximum concentration of iron in the body). In addition, before the study, you must follow these recommendations:
- iron-containing drugs should be discontinued a week before analysis;
- the day before the procedure, it is necessary to exclude the use of alcohol, smoking, the use of fatty and fried foods;
- fluorography and radiography are not recommended before analysis;
- 2-3 days before the analysis, it is recommended to limit physical activity;
- before the study, avoid emotional stress;
- the norm of serum iron in the blood of women can change due to pregnancy, therefore, a study on iron in dynamics is necessary;
- women should not be tested during menstruation.
Deciphering the results
The norm of iron in the blood depends primarily on gender and age. Deviations of a physiological nature are possible during the neonatal period, during pregnancy, or at different periods of the menstrual cycle. Consider normal rates for men, women, and children of different ages:
For women, micromol / l
For men, micromol / l
less than 1 month
1 month - 1 year
1 year - 5 years
15-18 years old
over 18 years old
The main signs of a low ferrum content are manifested by symptoms of anemia (headache, pallor, dry skin, hair loss, etc.). The causes of micronutrient deficiency are malnutrition, hereditary predisposition, impaired hematopoiesis, cancer and liver disease.
Excess of this microelement is diagnosed when its entry into the body significantly exceeds consumption, decay and excretion. The critical value is 30.4 μmol / L. The reasons for the high ferrum content are an overdose of iron-containing medications, frequent blood transfusions, chronic cholecystitis or hepatitis, and the premenstrual period.Attention!
