What is the normal range for hyaline casts in urine?
Casts: Casts are formed in the tubules of they kidney when the tubules secrete a protein called Tamm-Horsfall protein. The origin of the casts causes them to take on a tubular or hotdog-like shape. These casts are known as hyaline casts and can be present in normal adults on the order of 0-5 per LPF.
What is hyaline cast urine?
Casts are clusters of urinary sediment elements (red blood cells, white blood cells, fat bodies, etc.) wrapped in a protein matrix. Cast formation necessarily occurs in the kidney tubules, and the the contents of the casts indicate the nature of the abnormalities occurring in the kidney itself.What are the different types of casts in urine?

What causes uric acid crystals in urine?
Uric acid stones form when the levels of uric acid in the urine are too high, and/or the urine is too acidic on a regular basis. The formation of these types of stones can run in families. Inherited problems in how the body processes uric acid or protein in the diet can increase the acid in urine.
What urinalysis results indicate acute renal failure?

How are hyaline casts formed?
Hyaline casts are formed in the absence of cells in the tubular lumen. They consist of Tamm-Horsfall mucoprotein and have a smooth texture and a refractive index very close to that of the surrounding fluid. They are very difficult to see in wet preparations of urine and must be distinguished from mucus strands.
What is considered mild proteinuria?
Normally, you should have less than 150 milligrams (about 3 percent of a teaspoon) of protein in the urine per day. Having more than 150 milligrams per day is called proteinuria.
Is it normal to have crystals in urine?

Can leukocytes in urine mean STD?
Many common STIs, like gonorrhea and chlamydia, have few symptoms. As with other infections (vaginitis and UTIs), white blood cells respond to the site of the infection. These white blood cells can mix with urine, creating a cloudy appearance. STIs can also cause abnormal vaginal or penile discharge.
Can a UTI cause high white blood cell count?
The WBC count may or may not be elevated in patients with uncomplicated UTI, but it is usually elevated in patients with complicated UTIs.
