🧪 尿素氮/肌酐比值（BUN/Cr）计算器BUN to Creatinine Ratio Calculator
由血尿素氮（BUN）和血肌酐计算 BUN/肌酐比值，支持 mg/dL 和国际单位（尿素 mmol/L、肌酐 µmol/L），并给出常见的解读方向。Calculate the blood urea nitrogen (BUN) to creatinine ratio from mg/dL or SI units (urea mmol/L, creatinine µmol/L), with the usual direction of interpretation.
使用说明与常见问题How-to & FAQ
「尿素氮/肌酐比值（BUN/Cr）计算器」是什么？What is the BUN to Creatinine Ratio Calculator tool?
由血尿素氮（BUN）和血肌酐计算 BUN/肌酐比值，支持 mg/dL 和国际单位（尿素 mmol/L、肌酐 µmol/L），并给出常见的解读方向。Calculate the blood urea nitrogen (BUN) to creatinine ratio from mg/dL or SI units (urea mmol/L, creatinine µmol/L), with the usual direction of interpretation.
如何使用「尿素氮/肌酐比值（BUN/Cr）计算器」？How do I use the BUN to Creatinine Ratio Calculator tool?
在「尿素氮/肌酐比值（BUN/Cr）计算器」中，填写「单位」、「BUN（或尿素）」、「肌酐」等参数，结果会随输入实时计算并显示在下方。In the BUN to Creatinine Ratio Calculator: Fill in "Units", "BUN (or urea)", "Creatinine"; results are recalculated instantly as you type.
BUN/肌酐比值正常是多少？What is a normal BUN/creatinine ratio?
按 mg/dL 计算，常见正常范围约 10 : 1 到 20 : 1，各实验室略有不同。With both in mg/dL, the usual normal range is about 10 : 1 to 20 : 1; labs vary slightly.
国际单位怎么换算？How are SI units converted?
尿素 (mmol/L) × 2.801 = BUN (mg/dL)；肌酐 (µmol/L) ÷ 88.42 = 肌酐 (mg/dL)。换算后再相除。Urea (mmol/L) × 2.801 = BUN (mg/dL); creatinine (µmol/L) ÷ 88.42 = creatinine (mg/dL). Divide after converting.
结果可以代替医生的建议吗？Can this replace medical advice?
