Generally 45 mL
This test requires 5 ml of blood. Collection of the sample takes only a few minutes. A urine myoglobin test requires 1 ml of urine collected into a urine collection cup.
A serum hCG will be positive for pregnancy at 25mIU/ml, the urine test, although just as accurate needs a stronger concentration of 50mIU/ml to 100mIU/ml depending on the brand - this means the serum (blood) test will test positive 2 to 3 days sooner than urine.
Thirty to 60 mL is the standard amount of urine obtained in a midstream urine specimen. At least 3 mL are required to perform a urine culture. Twenty milliliters are necessary for routine urine studies.

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.
