Osmolality Calculator: Serum

**Serum Osmolality Calculator – Fast & Simple**

Calculate **serum osmolality** quickly and easily using the most common laboratory values: **sodium, glucose, and BUN**.

This simple **osmolality calculator** helps you calculate estimated serum osmolality from standard blood test results. Enter your values, select the appropriate units, and get the calculated result in **mOsm/kg**.

### Key features

• **Serum osmolality calculator**
Calculate estimated serum osmolality using sodium, glucose, and BUN.

• **Sodium unit selection**
Enter sodium in **mmol/L or mEq/L**.

• **Glucose conversion**
Enter glucose in **mg/dL or mmol/L**.

• **BUN conversion**
Enter BUN in **mg/dL or mmol/L**.

• **Automatic unit conversion**
The app converts glucose and BUN values between commonly used laboratory units.

• **Fast calculation**
Get the calculated osmolality result instantly after entering the required values.

• **Simple interface**
Designed for quick and straightforward serum osmolality calculations without unnecessary features.

### Serum osmolality formula

The calculator uses the commonly used calculated serum osmolality equation:

**Osmolality = 2 × Sodium + Glucose / 18 + BUN / 2.8**

The result is displayed in **mOsm/kg**.

### Useful for

Serum osmolality calculations involving:

• Sodium
• Glucose
• BUN (blood urea nitrogen)
• mmol/L
• mg/dL
• mEq/L
• mOsm/kg

Whether you need a quick **serum osmolality calculation** or a convenient **osmolarity calculator** for laboratory values, this app provides a simple way to enter the required values and calculate the result.

**Important:** This app is intended as a calculation and reference tool. It does not provide a medical diagnosis or treatment recommendation. Always interpret laboratory results in the appropriate clinical context and consult a qualified healthcare professional when necessary.
