If you are talking about three substances that are normally found in blood but not in urine, they are leukocytes, erythrocytes and glucose.
hemoglobin
The two main substances found in urine are water and waste products, such as urea, creatinine, and uric acid.
In a normal urine sample, you would typically find substances such as urea, creatinine, uric acid, and electrolytes like sodium and potassium. Additionally, urine may contain small amounts of proteins, hormones, and metabolic waste products. The presence of glucose, ketones, or significant protein levels can indicate underlying health issues. Overall, a healthy urine sample should be clear and pale yellow, with a balanced pH.
Substances like waste products (e.g., urea, creatinine), excess ions (e.g., sodium, potassium), and water are normally filtered out of the bloodstream in the nephron as part of the formation of urine.
The specific gravity of urine indicates the amount of dissolved substances in urine. It is a measure of the density of urine compared to water. A higher specific gravity indicates a higher concentration of dissolved substances, while a lower specific gravity indicates a lower concentration.
hemoglobin
Red blood cells, white blood cells, and platelets are typically present in blood but not normally found in urine.
Creatinine is normally found in urine. Blood proteins, red blood cells, and hemoglobin are all abnormal findings. White blood cells would indicate an infection.
Ions and nutrients
Protein is normally not found in urine because the kidneys function to filter out waste products and excess substances from the blood, while retaining essential proteins and molecules. When protein is present in urine, it may indicate an issue with the kidneys, such as damage to the filtering units that allow protein to leak into the urine.

Uremia
Yes, urea is a waste product that is normally found in urine. It is the main component of urine along with water and other waste products.
It means your urine contains ketones (acetone is a ketone). Ketones aren't normally found in urine, and are a sign of diabetes.
