Why is the balance of trace elements in the blood important?<\/strong><\/h2>\n

Microelements are indispensable components for the normal functioning of the body. They affect metabolism, the functioning of the cardiovascular, nervous and endocrine systems, the condition of bones, skin and immunity. An excess or deficiency of microelements can lead to serious disorders, so it is important to monitor their levels in the blood.<\/p>\n

A blood test for trace elements allows you to assess the general condition of the body, diagnose a deficiency or excess of important elements, and adjust your diet or prescribe treatment in a timely manner.<\/p>\n

\"Products<\/p>\n

Who needs it? blood test<\/a> for trace elements<\/strong><\/h2>\n

The study is recommended in the following conditions:<\/p>\n

    \n
  • chronic fatigue, drowsiness, headache<\/li>\n
  • hair loss, brittle nails, dry skin<\/li>\n
  • cramps, muscle weakness, numbness of the extremities<\/li>\n
  • frequent colds and viral diseases<\/li>\n
  • osteoporosis, joint pain, increased bone fragility<\/li>\n
  • cardiovascular disorders (arrhythmia, high blood pressure)<\/li>\n
  • indigestion, iron deficiency or anemia<\/li>\n
  • preparation for pregnancy or monitoring the level of trace elements in pregnant women<\/li>\n<\/ul>\n

    The analysis is also necessary for athletes, people with high levels of physical or mental stress, as well as those who follow strict diets.<\/p>\n

    What trace elements does a blood test determine?<\/strong><\/h2>\n

    Depending on the purpose of the study, the analysis may include various trace elements.<\/p>\n

    How is a blood test for trace elements performed?<\/strong><\/h2>\n

    The procedure is quite simple:<\/p>\n

      \n
    1. Venous blood sampling<\/strong> \u2013 is carried out in the laboratory by a specialist.<\/li>\n
    2. Sample study<\/strong> \u2013 is carried out using spectrometry or atomic absorption analysis.<\/li>\n
    3. Getting results<\/strong> \u2013 on average, it lasts from 1 to 5 days, depending on the number of trace elements being tested.<\/li>\n<\/ol>\n

      How to prepare for the test to get accurate results<\/strong><\/h2>\n

      For the reliability of the analysis, the following recommendations must be followed:<\/p>\n

        \n
      • do not eat 8-12 hours before the analysis<\/li>\n
      • avoid alcohol, coffee, strong tea, and fatty foods for 24 hours<\/li>\n
      • stop taking vitamin and mineral supplements for 3-5 days<\/li>\n
      • avoid physical exertion on the eve of the test<\/li>\n
      • do not smoke 2-3 hours before donating blood<\/li>\n
      • drink only clean water on the day of testing<\/li>\n<\/ul>\n

        How to decipher the analysis results<\/strong><\/h2>\n

        Normal values for trace elements may vary depending on age, gender, and physiological condition.<\/p>\n

        \n\n\n\n\n\n\n\n\n\n\n\n
        Microelement<\/strong><\/th>\nBlood norm<\/strong><\/th>\n<\/tr>\n<\/thead>\n

        Calcium (Ca)<\/td>\n2.1-2.6 mmol\/l<\/td>\n<\/tr>\n
        Zinc (Zn)<\/td>\n10-18 \u03bcmol\/l<\/td>\n<\/tr>\n
        Copper (Cu)<\/td>\n11-24 \u03bcmol\/L<\/td>\n<\/tr>\n
        Selenium (Se)<\/td>\n0.07-0.12 \u03bcmol\/l<\/td>\n<\/tr>\n
        Iodine (I)<\/td>\n0.02-0.06 \u03bcmol\/l<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

        In case of deviations from the norm, the doctor analyzes the possible causes and recommends diet correction or additional examination.<\/p>\n

        How to maintain optimal micronutrient balance<\/strong><\/h2>\n

        To prevent a deficiency or excess of trace elements, you should follow a balanced diet.<\/p>\n

        Foods rich in micronutrients<\/strong><\/h3>\n
          \n
        • Iron:<\/strong> beef, liver, spinach, legumes<\/li>\n
        • Magnesium:<\/strong> bananas, nuts, greens, dark chocolate<\/li>\n
        • Calcium:<\/strong> dairy products, almonds, sesame<\/li>\n
        • Zinc:<\/strong> seafood, pumpkin seeds, chicken<\/li>\n
        • Copper:<\/strong> nuts, liver, cocoa<\/li>\n
        • Selenium:<\/strong> garlic, Brazil nuts, eggs<\/li>\n
        • Iodine:<\/strong> seaweed, fish, dairy products<\/li>\n<\/ul>\n

          Sometimes, to restore the level of trace elements, it is necessary to take special supplements, but you should consult a doctor before using them.<\/p>\n

          Monitoring the level of trace elements in the blood helps prevent many diseases and maintain a healthy body. A blood test for trace elements is an effective way to learn about potential risks and take the necessary measures to correct nutrition or treatment in a timely manner.<\/p>","protected":false},"excerpt":{"rendered":"
