Blood aluminum (Al)

Aluminum is a trace element in the body, and aluminum that is normally ingested by the human body is mainly excreted by the kidneys. Patients with renal failure are prone to aluminum poisoning. The main source of aluminum in renal failure is dialysate during hemodialysis. Aluminum can be transferred across the membrane to the blood to increase blood aluminum. Determination of blood aluminum content plays an important role in the assessment of renal failure. Basic Information Specialist classification: growth and development check classification: biochemical examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Aluminum is a trace element in the body, and aluminum that is normally ingested by the human body is mainly excreted by the kidneys. Normal value: Plasma: 0.22-0.26umol/L Serum: 0-0.15umol/L Above normal: The increase is mainly seen in renal failure, aluminum poisoning and the like. negative: Positive: Tips: Do not eat too greasy, high-protein foods the day before the blood draw, avoid heavy drinking. The alcohol content in the blood directly affects the test results. After 8 pm on the day before the medical examination, you should start fasting for 12 hours to avoid affecting the test results. Normal value Atomic absorption spectrophotometry Plasma 0.22 ~ 0.26umol / L. Serum <0.15 umol/L. (Note the specific reference value depends on each laboratory.) Clinical significance The increase is mainly seen in renal failure, aluminum poisoning and the like. High results may be diseases: precautions for renal failure First, the precautions before blood draw 1, do not eat too greasy, high-protein food the day before the blood, to avoid heavy drinking. The alcohol content in the blood directly affects the test results. 2. After 8 pm on the day before the medical examination, you should start fasting for 12 hours to avoid affecting the test results. 3, should relax when taking blood, to avoid the contraction of blood vessels caused by fear, increase the difficulty of blood collection. Second, should pay attention after blood draw 1. After blood is drawn, local compression is required at the pinhole for 3-5 minutes to stop bleeding. Note: Do not rub, so as not to cause subcutaneous hematoma. 2, the pressing time should be sufficient. There is a difference in clotting time for each person, and some people need a little longer to clotting. Therefore, when the surface of the skin appears to be bleeding, the compression is stopped immediately, and the blood may be infiltrated into the skin due to incomplete hemostasis. Therefore, the compression time is longer to completely stop bleeding. If there is a tendency to bleed, the compression time should be extended. 3, after the blood draw symptoms of fainting such as: dizziness, vertigo, fatigue, etc. should immediately lie down, drink a small amount of syrup, and then undergo a physical examination after the symptoms are relieved. 4. If there is localized congestion, use a warm towel after 24 hours to promote absorption. 3. Please inform the doctor about the recent medication and special physiological changes before the test. Inspection process After venous blood collection, the test was carried out to measure blood inorganic substances. Not suitable for the crowd Those without examination indications should not be tested. Adverse reactions and risks Discomfort: There may be pain, swelling, tenderness, and visible subcutaneous ecchymosis at the puncture site.
