Chelating agent lead drive test

The chelating agent lead-exchanging test is a provocation test or a lead metabolism test, and the lead load of the body is judged mainly by observing the lead-discharge reaction of the chelating agent CaNa2EDTA. Basic Information Specialist classification: urinary examination classification: urine / kidney function test Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: normal. Normal value: Urinary lead: 0-0.3mg/L Above normal: Lead poisoning can be diagnosed when lead exceeds 3.86 μmol/L (0.8 mg/L) or 4.82 μmol/L (1 mg/d). Mild poisoning can occur neurasthenia syndrome (such as dizziness, insomnia, fatigue, multiple dreams) and digestive symptoms (such as loss of appetite, nausea, abdominal discomfort); anemia occurs when heavier anemia, abdominal cramps; Lead paralysis or toxic encephalopathy. negative: Positive: Tips: Actively cooperate with the doctor's work requirements. Normal value Its urine lead 1.45 μmol/L (0.3 mg/L) is the upper limit of normal value. Clinical significance Abnormal results: Lead poisoning can be diagnosed if the lead in urine exceeds 3.86 μmol/L (0.8 mg/L) or 4.82 μmol/L (1 mg/d). Mild poisoning can occur neurasthenia syndrome (such as dizziness, insomnia, fatigue, multiple dreams) and digestive symptoms (such as loss of appetite, nausea, abdominal discomfort); anemia occurs when heavier anemia, abdominal cramps; Lead paralysis or toxic encephalopathy. People who need to be examined: patients with lead poisoning. High results may be diseases: lead poisoning in children, lead poisoning precautions Forbidden before examination: empty the bladder. Requirements for inspection: Actively cooperate with the doctor's work requirements. Inspection process The patient was evacuated before the test. CaNa2EDTA was administered intramuscularly at a dose of 500 mg/m2 (usually formulated with 0.5% concentration of procaine to reduce pain during intramuscular injection). The urine was collected for 8 hours in a lead-free vessel, and the urine volume (L) and urine lead concentration (ug/L) were measured for 8 hours. Not suitable for the crowd There are no taboos. Adverse reactions and risks No.
