CHEMICAL EXAMINATION Flashcards
These are used to perform the routine chemical test on urine
Reagent Strips
TRUE OR FALSE: One of example of Care of Reagent Strips is exposing to temperatures below 30’C. The test open bottles of reagent with known controls are tested every 12 hours.
BOTH STATEMENT FALSE: Reagents strips are with positive and negative controls is tested every 24 hours. Reagents Strips shouldn’t be stored to below 30’C Temperatures.
Medically Significant Chemical Analytes
- pH
- Protein
- Glucose
- Ketones.
- Blood
- Bilirubin
- Urobilinogen
- Nitrite
- Leukocytes
- Specific Gravity
The most indicative of renal disease is the ________ determination
PROTEIN
TRUE OR FALSE: Tamm-Horsfall protein (uromodulin) is found in multiple myeloma and leukemias.
FALSE: Bence Jones Protein are the one found in multiple myeloma and leukemias.
This protein originated in the urinary tract
Uromodulin (Tomm Harshall Protein)
Cofirmatory Test used in Glucose detection
BENEDICT’S TEST
This Examination aids in the differentiation of hemoglobinuria and hematuria
Microscopic Examination
REAGENT STRIP COLOR REACTION OF KETONES AND LEUKOCYTE ESTERASE
PURPLE
PRINCIPLE TEST USED FOR GLUCOSE
DOUBLE SEQUENTIAL ENZYME REACTION
TRUE OR FALSE: Greiss’s Reaction is the principle test used for Bilirubin.
FALSE: Greiss’s Reaction is the Principle test used for NITRITE
What is the Reading time of Blood for Reagent strips?
60 Seconds
TRUE OR FALSE: The color of Reagent Strip Reaction for Bilirubin is Purple
FALSE: The color of reaction for Bilirubin is tan or pink to violet.
Identification: What is the principle test used for SPECIFIC GRAVITY
pka change of polyelectrolyte
TRUE OR FALSE: Theoritically, If a urine that indicate a 1.000 reading for Specific Gravity is not a URINE, but the Reagent strips can still detect the these values.
TRUE
Which of the following Reagent strip test can be affected by ascorbic acid, resulting in falsely low or False negative results.
BLOOD
GLUCOSE
BILIRUBIN
NITRITE
NITRITE
This two dyes are used as double indicator system used by commercial Reagent strips to determine urine pH
Methyl Red and Bromthymol Blue
SITUATIONAL:
What will happen if the Reagents after remaining in the urine for too long
The Reagents containing the strips will leach off - windows frame phenomenon.
SITUATIONAL:
The patients’ ate meat before sending it’s urine to the lab, what would be concentration of the urine?
The urine will be acidic, but if the patient ate vegetables the urine would be basic, with an exception of cranberry juice.
COMPLETE THE TABLE:
_______ - 30 SECONDS - DIAZ REACTION - _______
Bilirubin - tan or pink to violet.
