WBC's (pus) Glucose, bile pigments or blood proteins :)
If protein, glucose or white blood cellsappear in urine, it's a red flag.
Blood, proteins, and sugars are absent from the filtrate and urine of a healthy adult. If any of these are present it is a sign that something is not right and should be addressed right away.
Red blood cells are absent from the glomerular filtrate because they are too large to pass through the filtration membrane in the kidneys, which only allows small molecules like water, ions, and waste products to pass through. The presence of red blood cells in the filtrate could indicate damage to the filtration membrane.
Protein is typically absent in glomerular filtrate and urine due to the selective permeability of the glomerular filtration barrier, which consists of endothelial cells, a basement membrane, and podocytes. These structures prevent large molecules like proteins from passing through while allowing smaller molecules and water to filter through. Additionally, any small amounts of protein that may enter the filtrate are usually reabsorbed by renal tubules before urine formation. Therefore, healthy kidneys maintain minimal to no protein levels in urine.
Glucose is absorbed in the nephron of the kidney, if it is present in very high amounts or unable to be reabsorbed, like with diabetes, it will be present in urine.

I have heard it attributed to director Kurosawa's wife Yoko Yaguchi.
Absent means not in attendance. You can be absent from school, be absent minded or absent in physical presence for example.
The past tense of 'is absent' is 'was absent'. e.g. "Tim was absent that day."
62.5% of the class was absent if five eighths of the class is absent.
Compounds and substances are practically synonyms; a compound or substance may be impure (contain impurities) or pure ( the impurities are only as traces or absent).
