What is the correct interpretation by the nurse. Urine testing for diabetic analysis. What is a urinalysis? For the patient in case 1, because of his age, clinical history, and lack of other clear causes, the most appropriate course of action is to obtain blood urea nitrogen and creatinine levels, perform computed tomographic urography, and refer the patient for cystoscopy.5 An algorithm for diagnosis, evaluation, and follow-up of patients with asymptomatic microscopic hematuria is presented in Figure 1.5 The AUA does not recommend repeating urinalysis with microscopy before the workup, especially in patients who smoke, because tobacco use is a risk factor for urothelial cancer (Table 3).5, A previous article in American Family Physician reviewed the American College of Radiology's Appropriateness Criteria for radiologic evaluation of microscopic hematuria.8 Computed tomographic urography is the preferred imaging modality for the evaluation of patients with asymptomatic microscopic hematuria.5,8 It has three phases that can detect various causes of hematuria. If urine or other tests reveal high levels of protein, glucose, or ketones, the person should take measures to prevent any problems from getting worse. All Rights Reserved. E. Obtain a serum creatinine level to evaluate for chronic kidney disease. This can be caused by: It can also be caused by some genetic conditions, including: Alimentary glycosuria can happen when you eat lots of carbohydrates at a meal. Chronically high blood sugar levels are toxic to your blood vessels, causing them to narrow and become more clogged over time.

Urinalysis with microscopy has proven to be an invaluable tool for the clinician. It is unwise to assume that benign prostatic hyperplasia is the explanation for hematuria, particularly because patients with this condition typically have risk factors for malignancy. In this condition, lowmolecular-weight proteins predominate over albumin and rarely exceed 2 g per day. Glucose normally is filtered by the glomerulus, but it is almost completely reabsorbed in the proximal tubule. Some people dont know they have glycosuria until they have a urine test done., Glycosuria happens when you have glucose, or other sugars like lactose, fructose, or galactose, in your urine. These cells are smaller and rounder than squamous cells, and they have larger nuclei. It's dipped into your urine, and the chemicals on the stick react and change color if levels are above normal.

Explain Ans: 2)As a person ages, nephron tubules lose some of their ability to concentrate urine. A urine glucose test may also be used to help screen kidney function and damage in diabetes. Over time, if its not treated, it can cause some symptoms, including: The treatment for glycosuria depends on the cause. This situation initially results in alkaline urine, but as the filtered load of bicarbonate decreases, the urine becomes more acidic. The excess of glucose produced by the insulinoma impairs the exit of glucose out of the cell leading to decreased levels of glucose in the blood. Your blood carries glucose to your cells.

Are any of these substances abnormal in urine? If your levels are high, your healthcare provider will recommend a blood glucose test to confirm the diagnosis.

Glucose is a type of sugar. If these are over 240 milligrams per deciliter (mg/dl), the ADA recommend testing for ketones. In lupus treatment, a urinalysis is often used to monitor protein leakage and identify and assess urinary tract infections (UTIs). Further evaluation of patients with glomerular and nonglomerular hematuria should include determination of renal function and 24-hour urinary protein or spot urinary protein-creatinine ratio.

Normally, your kidneys absorb the sugar from any liquid passing through them, but with glycosuria, the kidneys. Dipstick tests for trace amounts of protein yield positive results at concentrations of 5 to 10 mg per dLlower than the threshold for clinically significant proteinuria.15 A result of 1+ corresponds to approximately 30 mg of protein per dL and is considered positive; 2+ corresponds to 100 mg per dL, 3+ to 300 mg per dL, and 4+ to 1,000 mg per dL.31,32 Dipstick urinalysis reliably can predict albuminuria with sensitivities and specificities of greater than 99 percent.4 Asymptomatic proteinuria is associated with significant renal disease in less than 1.5 percent of patients.4,33.

The strips change color if a substance is present at a level that is above normal. An infection may make urine look cloudy. Casts in the urinary sediment may be used to localize disease to a specific location in the genitourinary tract (Table 6).38 Casts, which are a coagulum of Tamm-Horsfall mucoprotein and the trapped contents of tubule lumen, originate from the distal convoluted tubule or collecting duct during periods of urinary concentration or stasis, or when urinary pH is very low.
