Chemical urinalysis QA guidelines
- Make sure all pads are covered
- Do not leave caps off
- Do not touch pads
- Do not combine strips
- Dont use expired strips
- Do not refrigerate
- Keep in cool dry place
Results from breakdown of biliruben in colon by bacteria
Urobilinogen
Normally too large to pass through glomerulus rebal disease: proteinuria
Protein
Intensely yellow pigmented substance not soluble in water (liver)
Biliruben
Bacteria nitrate to nitrite
Nitrites
Weight of urine as compared to equal volume of water
Specific gravity
Products of fat metabolism oxidized by muscles
Ketone
White blood cells in urine
Leukocyte
Most important aid in identification of urine crystals
ph
Hemoglobin, myoglobin,erythrocytes
Blood
Sugar tested for in urine
Glucose
Guidelines to helphigh quality results when using reagent test strips
Ensure urine stick is completely covered
Confirmatory for biliruben
Ictotest
Confirmatory for reducing sugar/substance
Clinitest
Confirmatory for ketones
Acetest
Red blood cells in urine
Hematuria
What results could be positive on a reagent strip to indicate a UTI
blood, protien, nitrites,leukocytes
What results could be positive if a patient has diabetes?
Glucose,ketones
Positive biliruben test results could be caused by what liver diseases?
Hepatitis, sclerosis, jaundice
Positive erythrocytes(RBC) in urine could be an indication of?
Kidney stones
What does presence of nitrites indicate in fresh urine?
Bacteria
Qualitative and semi quantitative urine tests
Qualitative-indicates if particular analyte is present
Semiquantative- determines approximate quantity of an analyte
Procedure for preparing urine for microscopic examination
12 mL, 5 mins in centrifuge, mix up sediment and put into 10 slides, take out after 5 mins and pour off supernatant
