Urinalysis by Apollo
| Question | Answer |
|---|---|
| Cloudiness im a freshly voided urine could indicate the presence of | White blood cells |
| In acute febrile disease urine may acquire a reddish color due to | Uroerythrin |
| A smoky red brown urine should be suspected of containing | Hemoglobin |
| A urine that turns brown black may contain | Homogenistic acid |
| When a urinw specimen is allowed to stand at room temperature , which does not occur? ( disappearance of formed elements, elevation in ph, false positive glucose, false positive protein) | False positive glucose |
| The first morning specimen of urine is often tested because tbis specimen | Contains most formed elements |
| Highest specific gravity to which the kidney is able to concentrate urine | 1.040 |
| All of the following systems may be used to determine the specific gravity of urine except (spectrophotometer, refractometer, T-S meter, reagent test strip) | Refractometer |
| At a temperarure of 26c a urine specific gravity reads 1.014. If a temperature correction is employed what would the corrected specific gravity be? | 1.016 |
| A refractometer would be used in urinalysis department to measure | Specific gravity |
| If the plasma osmolality is normal (185 mOsm/kg water, the urine osmolality should be atleast | Three times that of plasma |
| Which of these plasma substances is not normally filtered through the glomerulus in significant amount (creatinine, glucose, protein, urea) | Protein |
| Precipitation tests for urine protein do not include which of the following (acid and heat, dipstick, sulfosalicylic acid, trichloracetic acid) | Dipstick |
| The normal excretion of small amounts of protein in urine is considered to be less than what daily amount | 150 mg |
| All of the following apply to dipstick test for urine protein, based on the protein error of indicators except | The color change in the stick is due to ph change |
| Which does not apply to urine protein estimation by the dipstick method | Bence jones rotein interferes with measurement of albumin |
| Which of the following is true of detection of urinary glucose | Any reducing substance can give a false positive reaction with the copper reduction method for glucose |
| The enzyme dipstick test for glucose in urine has a sensitivity of | 100 mg/dl |
| What may give a false positive reaction on glucose dipstick | Oxidizing agent |
| For fructose detection, what reagent is employed | Resorcinol and hydrochloric acid |
| What is the most definitive test for phenylketonuria (PKU) | Direct measurement of blood level of phenylalanine |
| The urine dipstick tests for occult blood depend on the fact that | Hemoglobin can act as peroxidase |
| In the test of heme pigment in urine | Prior removal of bilirubin is necessary |
| The addition of fouchet's reagent to the barium chloride precipitate of urine results in a green color in the presence of | Bilirubin |
| The addis count is the semiquantotave estimate of the 12 hr excretion of which urinary constituent | Casts, red blood cells, and white blood cells |
| The most common use of polarized microscopy is to visualize | Lipids (fats) |
