🧪 AST/ALT 比值计算器（De Ritis 比值）AST/ALT Ratio Calculator (De Ritis Ratio)

使用说明与常见问题How-to & FAQ

「AST/ALT 比值计算器（De Ritis 比值）」是什么？What is the AST/ALT Ratio Calculator (De Ritis Ratio) tool?

输入同一次化验的 AST 和 ALT（U/L），计算 AST/ALT（De Ritis）比值，并对照常见参考上限标出是否升高，附上文献中常见的解读方式。仅供了解，结果需由医生结合病史解读。本地处理。Enter AST and ALT (U/L) from the same blood test to get the AST/ALT (De Ritis) ratio, see whether each is above a common upper reference limit, and read how the ratio is usually discussed in the literature. For information only; a clinician must interpret results with your history. Processed locally.

如何使用「AST/ALT 比值计算器（De Ritis 比值）」？How do I use the AST/ALT Ratio Calculator (De Ritis Ratio) tool?

在「AST/ALT 比值计算器（De Ritis 比值）」中，填写「AST（U/L）」、「ALT（U/L）」、「AST 参考上限（可选）」、「ALT 参考上限（可选）」等参数，结果会随输入实时计算并显示在下方。In the AST/ALT Ratio Calculator (De Ritis Ratio): Fill in "AST (U/L)", "ALT (U/L)", "AST upper limit (optional)", "ALT upper limit (optional)"; results are recalculated instantly as you type.

这个比值叫什么？What is this ratio called?

AST/ALT 比值也称 De Ritis 比值，1957 年由 De Ritis 提出。两项必须来自同一次化验、使用相同单位。The AST/ALT ratio is also called the De Ritis ratio, after De Ritis in 1957. Both values must come from the same test in the same units.

参考上限是多少？What are the reference limits?

不同实验室不同，常见 AST 约 40 U/L 以下、ALT 约 40–56 U/L 以下，有些指南建议更低的 ALT 上限。请以化验单上的范围为准，本页可自行填写。Labs differ; AST under about 40 U/L and ALT under about 40–56 U/L are common, and some guidelines suggest lower ALT limits. Use the range on your report, which you can enter here.

比值大于 2 就是酒精性肝病吗？Does a ratio above 2 mean alcohol-related liver disease?

不一定。这只是文献中常见的提示，肌肉损伤、肝硬化等其他情况也会使比值升高。需要医生结合症状和其他检查判断。Not necessarily. It is only a commonly cited pointer; muscle injury, cirrhosis and other conditions also raise the ratio. A clinician has to judge it with symptoms and other tests.

能举个计算实例吗？Can you show a worked example?

例如在「AST/ALT 比值计算器（De Ritis 比值）」中填 AST（U/L） = 40，ALT（U/L） = 20，结果区显示：AST/ALT 比值：2；常见解读：≥ 2：AST 明显占优，常被描述为提示酒精性肝病；AST：在参考上限内；ALT：在参考上限内；⚠ 比值本身不能诊断疾病；两项都正常时比值意义很小。请让医生解读。For example, entering AST (U/L) = 40, ALT (U/L) = 20 in the AST/ALT Ratio Calculator (De Ritis Ratio) gives: AST/ALT ratio: 2; Usual reading: 2 or more: AST clearly predominant, often described as suggesting alcohol-related liver disease; AST: Within the upper limit; ALT: Within the upper limit; ⚠ The ratio alone diagnoses nothing, and it means little when both…

哪些输入会被检查？Which inputs are validated?

「AST/ALT 比值计算器（De Ritis 比值）」会检查这些输入——「AST（U/L）」：必须填写，不能为负数；「ALT（U/L）」：必须填写，须大于 0；「AST 参考上限（可选）」、「ALT 参考上限（可选）」：不能为负数；绝对值超过 10¹⁵ 的数也会被拒绝。不符合时结果区显示具体提示，不会给出数字。The AST/ALT Ratio Calculator (De Ritis Ratio) checks its inputs — "AST (U/L)": required, cannot be negative; "ALT (U/L)": required, must be greater than 0; "AST upper limit (optional)", "ALT upper limit (optional)": cannot be negative; numbers above 10¹⁵ in absolute value are rejected too. When a value fails, the result area names the problem instead of showing a number.

有哪些选项可以调整？What options can I adjust?

「AST/ALT 比值计算器（De Ritis 比值）」的设置：「AST（U/L）」默认 40；「ALT（U/L）」默认 20；「AST 参考上限（可选）」默认 40；「ALT 参考上限（可选）」默认 40。每次生成结果都按当前设置处理。Settings in the AST/ALT Ratio Calculator (De Ritis Ratio) — "AST (U/L)" default 40; "ALT (U/L)" default 20; "AST upper limit (optional)" default 40; "ALT upper limit (optional)" default 40. The result always uses the current settings.

结果可以代替医生的建议吗？Can this replace medical advice?

不能。「AST/ALT 比值计算器（De Ritis 比值）」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 AST/ALT Ratio Calculator (De Ritis Ratio) gives estimates from common formulas; individuals differ, so consult a doctor or professional for health decisions.

「AST/ALT 比值计算器（De Ritis 比值）」免费吗？需要注册吗？Is the AST/ALT Ratio Calculator (De Ritis Ratio) free? Do I need an account?
