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 isn't normally found in urine, because so many people these days are on Methamphetamine, a very strong drug used by individuals seeking an easy escape. If this drug is abused, the protein from the mitochondria in your cells don't diffuse through the cells into the stream of urine. -Jericho

Uremia
Urea is the chief solid component of mammalian urine; synthesized from ammonia and carbon dioxide and used as fertilizer and in animal feed and in plastics.
It means your urine contains ketones (acetone is a ketone). Ketones aren't normally found in urine, and are a sign of diabetes.
