If you are talking about three substances that are normally found in blood but not in urine, they are leukocytes, erythrocytes and glucose.
hemoglobin

A random urine specimen is a urine sample collected at any time without following a specific time schedule or fasting requirement. This type of specimen is commonly used for routine screenings or as a general sample to check for various medical conditions.
No, you do not need to empty the boric acid from a urine sample bottle before use. The boric acid acts as a preservative to keep the sample stable until it can be tested.

Creatinine is normally found in urine. Blood proteins, red blood cells, and hemoglobin are all abnormal findings. White blood cells would indicate an infection.
Uremia
it is abnormal and high and show kidney dis.
It means your urine contains ketones (acetone is a ketone). Ketones aren't normally found in urine, and are a sign of diabetes.
Strep infection is not diagnosed from a urine sample.
There are single-sample tests and split-sample tests. If you've got a split-sample test, the second half of the sample goes into the freezer for six months regardless. For single-sample and the other part of a split-sample test, they retain the sample if it tests positive, but if it tests negative they normally dump it.
Yes, creatinine is normally found in urine as it is a waste product produced by muscle metabolism. The level of creatinine in urine can be an indicator of kidney function.
Boric acid is used as a preservative in urine sample bottles to prevent the growth of bacteria and preserve the integrity of the sample for testing. It helps to maintain the pH of the urine and keep it stable until it can be analyzed.
