🦴 校正血钙计算器(白蛋白校正)Corrected Calcium Calculator
按 Payne 公式用白蛋白校正总血钙:校正钙 = 测得总钙 + 0.8 × (4.0 − 白蛋白)(mg/dL、g/dL),或国际单位 校正钙 = 总钙 + 0.02 × (40 − 白蛋白)(mmol/L、g/L)。Correct total serum calcium for albumin with the Payne formula: corrected Ca = measured Ca + 0.8 × (4.0 − albumin) in mg/dL and g/dL, or Ca + 0.02 × (40 − albumin) in mmol/L and g/L.

如何使用「校正血钙计算器(白蛋白校正)」?How do I use the Corrected Calcium Calculator tool?
在「校正血钙计算器(白蛋白校正)」中,填写「单位」、「测得总钙」、「白蛋白」、「正常白蛋白参考值」等参数,结果会随输入实时计算并显示在下方。In the Corrected Calcium Calculator: Fill in "Units", "Measured total calcium", "Albumin", "Normal albumin reference"; results are recalculated instantly as you type.
为什么要校正血钙?Why correct calcium for albumin?
血中约 40% 的钙与白蛋白结合。白蛋白低时总钙会偏低,但真正起作用的离子钙可能正常,所以用公式估算白蛋白正常时的总钙。About 40% of blood calcium is bound to albumin. With low albumin the total calcium reads low even if the active ionized calcium is normal, so the formula estimates what total calcium would be at a normal albumin.
公式是什么?What is the formula?
Payne 公式:校正钙 (mg/dL) = 总钙 + 0.8 × (4.0 − 白蛋白 g/dL);国际单位:校正钙 (mmol/L) = 总钙 + 0.02 × (40 − 白蛋白 g/L)。部分实验室用 4.4 g/dL 或其他参考值,可在「正常白蛋白参考值」中修改。Payne: corrected Ca (mg/dL) = total Ca + 0.8 × (4.0 − albumin g/dL); in SI units, corrected Ca (mmol/L) = total Ca + 0.02 × (40 − albumin g/L). Some labs use 4.4 g/dL or another reference, which you can change in the "Normal albumin reference" field.
结果可以代替医生的建议吗?Can this replace medical advice?
不能。「校正血钙计算器(白蛋白校正)」基于常用公式给出估算,个体差异较大,如有健康问题请咨询医生或专业人士。No. The Corrected Calcium Calculator gives estimates from common formulas; individuals differ, so consult a doctor or professional for health decisions.
