a. Metabolites of Lodine (etodolac)
b. Vaginal discharge
c. Bacterial overgrowth in specimen
d. Urinary tract infection
e. Bloody urine
f. Oxidizing contaminants (hypochlorite) or microbial peroxidase
g. Aminosalicylic acid, sufonamides

i. Protein
Match the urine test strip reagent pad on the left with the possible causes of false negative reactions/reduced levels on the right.
___ 1. Blood
___ 2. Leukocytes
___ 3. Nitrite
___ 4. Glucose
___ 5. Specific gravity
___ 6. Urobilinogen
a. Capotin (captopril)
b. Highly buffered alkaline urines
c. Indocin (indoxyl sulfate)
d. Shortened bladder incubation, dietary deficiency of nitrate, nonreductive pathological microbes
e. Ketones
f. High glucose or cephalaxin (keflex), oxalic acid, tetracycline
Explanation / Answer
a. Metabolites of Lodine (etodolac) -------> 7. Bilirubin (False positive reaction for bilirubin)
b. Vaginal discharge -----------------------> Protein (False positive reaction)
c. Bacterial overgrowth in specimen -----> 9. pH
d. d. Urinary tract infection -----------------> 4. Nitrite
h. Highly pigmented urine, levodopa metabolites, compunds containing sulfhydryl groups (2-mercaptoethane sulfonic acid) ------------------------------------> 5. Ketones
