+# CockCroft Gault Equation
+
+### CockCroft Gault Equation is an equation which is used to calculate the eGFR (Estimated Glomerular Filtration Rate) 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 GFR
+$$
+GFR = \frac{(140 - Age)}{(72 * Creatinine)} \times 0.85 \:\text{(if patient is female)}
+$$
+
+## 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 eGFR 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.)
