      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

      h. Highly pigmented urine, levodopa metabolites, compunds containing sulfhydryl groups (2-mercaptoethane sulfonic acid)

      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
