In todays era everyone found difficulty to calculate test values so here we have best solution How to Calculate Bun from Urea and Creatinine
Introduction to kidney Test
I am a microbiologist at Shadab Lab, where I perform various tests to assess human health. The BUN test is used to check kidney health and determine if the kidneys are functioning properly or facing critical issues. This test measures the level of Urea Nitrogen in the blood; high urea levels can be dangerous for kidney health.
What Is BUN?
BUN (Blood Urea Nitrogen) reflects the amount of nitrogen in the blood produced during protein breakdown. Kidneys filter this nitrogen and remove it through urine. High BUN levels may indicate kidney dysfunction.
Difference Between Urea and Creatinine
| Urea | creatinine |
Its called the waste product which is protein metabolism take place which is filtered by kidney from blood and excrete through urine. | Another waste product produced from muscle breakdown, which the kidneys remove from the blood. |
Formula for Calculating BUN
Formula for Calculating BUN
BUN is calculated as:
BUN = Urea (mg/dL) ÷ 2.14
For the BUN/Creatinine Ratio:
BUN/Creatinine Ratio = BUN ÷ Creatinine
A normal ratio ranges between 10:1 and 20:1. Values outside this range may suggest dehydration or kidney issues..Example Calculation
Assume:
- Urea = 42 mg/dL
- Creatinine = 1.2 mg/dL
Step 1: Calculate BUN
BUN = 42 ÷ 2.14 = 19.63 mg/dL
Step 2: Calculate BUN/Creatinine Ratio
19.63 ÷ 1.2 = 16.36
This result falls within the normal range, indicating healthy kidney function.
This ratio falls within the normal range, indicating that the kidneys are functioning properly.
Note: If manual calculations are challenging, use a BUN calculator by inputting values for instant results.
FAQS
What is the formula for calculating BUN?
The basic Formula used everywhere is UN (mg/dL) = urea (mmol/L) × 2.8
How to measure bun level ?
A simple blood test can measure your BUN levels by checking the amount of urea nitrogen in your blood.
Why is urea called BUN?
A BUN (Blood Urea Nitrogen) test checks how much urea nitrogen is in your blood. Urea nitrogen is a waste product your body makes when it breaks down protein.
How to calculate urea to BUN?
To calculate BUN from urea, divide the urea value (mg/dL) by 2.14.
