Reagent strips these examine = pH, protein, glucose, ketones, blood, bilirubin, urobilinogen, nitrite, leukocytes, specific gravity Reagent strip bottles store these at room temperature QC is done with positive and negative controls every 24 hrs Confirmatory testing using different methods to detect the same substances pH kidneys and lungs regulate this acid base in the body. Clinical significance of pH aids in determining disorders of the metabolic or respiratory origin. Urinary pH may in...

Given the following dry reagent strip urinalysis results, select the most appropriate course of action: pH = 8.0 Protein = 1+ Glucose = Neg Blood = Neg Ketone = Neg Nitrite = Neg Bilirubin = Neg A. Report the results, assuming acceptable quality control B. Check pH with a pH meter before reporting C. Perform a turbidimetric protein test, instead of the dipstick protein test, and report D. Request a new specimen - ANSWERSC Highly buffered alkaline urine may cause a false-positive result...

Why is the first-voided morning urine specimen the most desirable specimen for routine urinalysis? A. Most dilute specimen of the day and therefore any chemical compounds present will not exceed the detectability limits of the reagent strips B. Least likely to be contaminated with microorganisms because the bladder is a sterile environment C. Most likely to contain protein because the patient has been in the orthostatic position during the night D. Most concentrated specimen of the day and t...

IGCSE Biology Exam - Paper 6 Revision Notes BIO Enzyme activity lab: 2H2O2 (l) → 2H2O (l) + O2 (g) This reaction can be catalysed by an enzyme (catalase) or by a non- biological catalyst (Manganese IV oxide) 1. Put 3cm2 of hydrogen peroxide in a test tube. 2. Add fresh potato strips and shake gently. 3. Keep your thumb on top of the test tube, or use a stopper, to retain the gas. 4. Do the “glowing splint” test → the splint relights Positive control: repeat the original experime...
