Urinalysis (100% Correct Solutions)

Why is Urinalysis important? correct answers Urinalysis is an essential part of the medical examination of any patient with suspected kidney disease and provides important information about the patient. What's the procedure to collect a proper sample? correct answers It involves cleansing the external genitalia with a mild antiseptic solution first. During the collection, the initial portion of the urine stream is allowed to escape while the midstream portion is collected. What are you looking for in a unrine sample and what's the timeline in looking at it? correct answers The urine should be examined within an hour. If urine cannot be examined while fresh, refrigerate it to slow down the deterioration. Look for:(i) physical characteristics (ii) chemical analysis with a dipstick and (iii) microscopic examination of the urine sediment. What are the physical things you're looking for? Color? correct answers This includes: Color: Yellow, clear or straw is normal. Other colors are possible due to drugs or dyes or pathological conditions. What are the physical things you're looking for? Appearance? correct answers Normal is usually clear. Hazy urine may suggest cells or crystals. 'Smoky': urine in acute glomerulonephritis. Foamy: seen in proteinuric states. What are the physical things you're looking for? Specific Gravity? correct answers Specific gravity is the ratio of urine volume to weight of the same volume of distilled water. It is dependent on both the number of particles and weight of particles in solution. Urinary specific gravity is used to measure the concentrating and diluting power of the kidney. What are the physical things you're looking for? Specific Gravity range and when it's high? correct answers The normal range is 1.003-1.035 depending on hydration and urinary volume. It's high when (i) fluid intake is low or patient is dehydrated (and urine is concentrated) (ii) high molecular weight substances such as glucose or radiographic dye are present in urine.
