Grandma's temp at home read 99.6. went to dr. 20 minutes later, there it read 98.2. went home, took temp, it read 99.7. diagnosed with uti and put on cipro. same thing happened 4 days later. why is her temp reading so high at home?

Is UTI correct: How was diagnosis of UTI made? On a voided urine specimen, urine culture, or just the fever in an elderly woman? Although UTI are fairly common in elderly other things can cause fever too. Did she have any other voiding sx or abdominal pain or cough? I feel a woman especially an obese woman or elderly woman should have a cath urinalysis and culture to confirm an UTI. if negative look elsewhere
