# Model for End-stage Liver Disease (MELD) score
#### MELD score is a numerical value that is used to predict the 3-month mortality prediction risk of a patient. It is also used to prioritize patients for liver transplantations with higher score indicating a more urgent need.
### Parameters needed
| Parameter | Unit |
| --------- | ---- |
| Serum Bilirubin | mg/dL |
| Serum Creatinine | mg/dL |
| International Normalized Ratio (INR) | - |
### MELD Score interpretation table:-
| Score range | Mortality risk |
| ----------- | -------------- |
| less than 9 | Low risk (under 1.9%) |
| 10 to 19 | Low to Moderate (6.0% - 19.6%) |
| **20 to 29** | **Moderate risk (19.6% - 52.6%)** |
| **30 to 39** | **High risk (52.6% - 71.3%)** |
| **more than 40** | **Extremely high risk (71.3% - 100%)** |
### Formula to calculate MELD:-
The MELD score is calculated using the following formula:-
$$
\textbf{MELD} = (9.57 \times \ln(\text{Serum Creatinine})) + (3.78 \times \ln(\text{Serum Bilirubin})) + (11.2 \times \ln(\text{INR})) + 6.43
$$
### Notice:-
The MELD score is not considered accurate for advanced liver diseases. Other calulcators like MELD-Na should be used before taking clinical decisions

# CockCroft Gault Equation
### CockCroft Gault Equation is an equation which is used to calculate the CrCl (Creatinine Clearance) of a patient
### Unit:- mL/min
#### It takes the following parameters
| Parameter | Range | unit |
| --------- | ----- | ---- |
| Age | 18-95 | - |
| Serum Creatinine | 0.2 - 20 | mg/dL |
| weight | 10 - 100 | kg |
| Gender | - | - |
### Formula
#### It uses the following formula to calculate the CrCl
$$
CrCl = \frac{(140 - Age)}{(72 \times S. Creatinine)} \times 0.85 \text{(if patient is female)}
$$
## Interpretation
#### GFR can be interpreted by using the following table
| Range of GFR | Stage | Message |
| ------------ | ----- | ------------------ |
| more than 90 mL/min | CKD Stage 1 | Renal Function is normal |
| 60 - 90 mL/min | CKD Stage 2 | Renal Function is slightly reduced |
| **45 - 60 mL/min** | **CKD Stage 3A** | **Renal Function is moderately reduced** |
| **30 - 45 mL/min** | **CKD Stage 3B** | **Renal Function is significantly reduced** |
| **15 - 30 mL/min** | **CKD Stage 4** | **Renal Function is largely reduced** |
| **less than 15 mL/min** | **CKD Stage 5 / ESRD** | **Renal Function is severely reduced** |
### Notice:-
#### This equation of calculating Creatinine Clearance is not as accurate, other equations like MDRD and CKD-EPI are recommended. Equation is not reliable in the cases of AKI (Acute Kidney Injury). Consultation with a Nephrologist is always recommended. No diagnosis should be made just on the basis of a medical calculator. Other clinical clues are to be taken into account (Urinalysis, UACR(Urine Albumin to Creatinine Ratio) etc.)
