Apob/A1 Ratio Calculator

Formula

The formula to calculate the Apob/A1 ratio is:

\[ R = \frac{A_p}{A_1} \]

Where:

\(R\) is the Apob/A1 ratio
\(A_p\) is the Apob value in mg/dL
\(A_1\) is the A1 value in mg/dL

What is Apob/A1 Ratio?

The Apob/A1 ratio is a clinical marker used to assess cardiovascular risk. Apob (Apolipoprotein B) and A1 (Apolipoprotein A1) are proteins associated with lipoproteins in the blood. Apob is found in low-density lipoprotein (LDL) particles, which can contribute to plaque buildup in arteries, while A1 is found in high-density lipoprotein (HDL) particles, which help remove cholesterol from the bloodstream. A higher Apob/A1 ratio indicates a higher risk of cardiovascular disease, as it suggests a higher proportion of LDL relative to HDL.

Example Calculation 1

Let's assume the following values:

Apob Value (A_p) = 100 mg/dL
A1 Value (A₁) = 50 mg/dL

Using the formula:

\[ R = \frac{100}{50} = 2.00 \]

The Apob/A1 Ratio is 2.00.

Example Calculation 2

Let's assume the following values:

Apob Value (A_p) = 80 mg/dL
A1 Value (A₁) = 40 mg/dL

Using the formula:

\[ R = \frac{80}{40} = 2.00 \]

The Apob/A1 Ratio is 2.00.
