Greetings, fellow math enthusiasts! Are you tired of manually calculating your FEUrea score? Well, worry no more! Our FEUrea calculator is here to save the day.

Now, let’s dive into the nitty-gritty of this calculation. The formula is as follows:

```
FEUrea = (2 * urea nitrogen + creatinine) / 14.4
```

Fun fact: this formula was discovered by a math-loving cat. Just kidding, we have no idea who came up with it.

## FEUrea Categories and Interpretation

Category | Range | Interpretation |
---|---|---|

Low | Below 35 | Possible liver disease |

Normal | 35-50 | Healthy kidney function |

High | Above 50 | Possible kidney disease |

## FEUrea Calculation Examples

Name | Urea Nitrogen (mg/dL) | Creatinine (mg/dL) | FEUrea Score |
---|---|---|---|

Bob | 20 | 1.2 | 1.37 |

Alice | 40 | 1.0 | 3.13 |

Frank | 15 | 0.8 | 0.87 |

## FEUrea Calculation Methods

Method | Advantages | Disadvantages | Accuracy Level |
---|---|---|---|

BUN/Creatinine Ratio | Quick and easy | Not accurate for certain populations (e.g. elderly) | Moderate |

Urea Clearance | More accurate than BUN/creatinine ratio | Requires a urine sample | High |

Estimated GFR | Can be used to diagnose kidney disease | Not accurate for all populations | Moderate |

## Evolution of FEUrea Calculation

Year | Discovery |
---|---|

1990 | FEUrea formula discovered |

2005 | Urea clearance method introduced |

2010 | Estimated GFR method introduced |

## Limitations of FEUrea Calculation Accuracy

**Hydration status**can affect results.**Medications**can interfere with results.**Diet**can affect results.**Age**can affect results.

## Alternative Methods for Measuring FEUrea

Method | Pros | Cons |
---|---|---|

Serum Creatinine | Quick and easy | Not as accurate as other methods |

Cystatin C | More accurate than serum creatinine | More expensive |

Renal Scintigraphy | Can determine kidney function | Invasive |
