Urinalysis - After the patient provides a urine specimen, it is sent to the lab for analysis using a variety of methods including urine dipstick testing and microscopic examination. Because the kidney is responsible for making urine , analyzing the urine directly can provide crucial data that can help the physician diagnose nephritic syndrome ...
The first test will be a urinalysis to test for high levels of proteins, [35] as a healthy subject excretes an insignificant amount of protein in their urine. The test will involve a 24-hour bedside urinary total protein estimation. The urine sample is tested for proteinuria (>3.5 g per 1.73 m 2 per 24 hours).
Increasing the urine pH to a value higher than 7.0 may increase the risk of calcium phosphate stone formation, though this concept is controversial since citrate does inhibit calcium phosphate crystallization. Testing the urine periodically with nitrazine paper can help to ensure the urine pH remains in this optimal range. Using this approach ...
Urinary symptoms can include blood in the urine, increased urinary frequency, urgency, occasional incontinence, difficulty voiding, and burning sensation. Emphysematous cystitis is often indicated in patients who have air in the urine. [6] In some cases, emphysematous cystitis can cause thickening of the bladder wall. [7]
A urinalysis is helpful even when not showing any pathology, as this finding suggests an extrarenal etiology. Proteinuria and/or urinary sediment usually indicates the presence of glomerular disease. Hematuria may be caused by glomerular disease or by a disease along the urinary tract. [citation needed]
Other tests helpful in the diagnosis include urine protein, urinalysis, serum albumin, and serum lipids. [2] A clinical picture of proteinuria , low blood protein levels (albumin, antibodies), and high blood cholesterol would support a diagnosis of FSGS, although these do not help to distinguish between FSGS and other causes of proteinuria.
Urine pH may be monitored to help prevent the formation of kidney stones or to avoid side effects of some drugs, [68] such as high-dose methotrexate therapy, in which crystals that cause kidney damage can form if the urine is acidic. [69] If microscopy is performed, knowing the pH of the sample helps to identify any crystals that might be ...
Hypercalciuria is the condition of elevated calcium in the urine. Chronic hypercalciuria may lead to impairment of renal function, nephrocalcinosis, and chronic kidney disease. Patients with hypercalciuria have kidneys that excrete higher levels of calcium than normal, for which there are many possible causes. Calcium may come from one of two ...
