Generally 45 mL
Most healthcare facilities require at least 30 milliliters (mL) of urine for a urine sample. This amount provides an adequate volume for testing while ensuring accurate results. It’s important to follow specific instructions provided by your healthcare provider for proper collection.

To calculate the grams of urea in 50 ml of urine where 1.8% is urea, first convert the ml to grams using the density of urine (about 1 g/ml). Then, multiply the volume of urine in grams by the percentage of urea (0.018) to find the grams of urea present in 50 ml of urine.
The density of normal urine is around 1.010 g/mL. Comparing the weights to volumes, the first sample has a density of 1.001 g/mL, the second has a density of 1.020 g/mL, and the third has a density of 1.036 g/mL. Therefore, the second sample with a density of 1.020 g/mL represents normal urine in terms of density.
Nearly 1200-1500mL urine is excreted per day.
It's not legal or condoned. It also puts you at some risk--if you're at 500 ng/ml and you mix your sample with four clean friends' samples, instead of just you being hot all your friends are hot too.
