Why Does My Urine Test Show Positive In Office And Negative In Lab?
Hi my daughter is 7 and she keeps getting the feeling like she has a uti when she has these symptoms she also has blood in her urine. When she goes to the doctors and does a urine it shows positive for infection in the office but negative at the lab and it has happened alot. We had her see a kidney specialist and they did and ultrasound and she said it looked normal. Can u please help me in what this problem can possibly be?

Hello and welcome to HCM,
Presence of blood in urine does not suggest urinary tract infection (UTI).
UTI is characterized by burning urination and increased frequency of urination most commonly.
If burning urination is present, UTI is likely.
You need to get a urine routine examination, esterase test and nitrite test.
If the above tests are positive for infection, UTI is confirmed and a course of antibiotic is required.
In case none of the tests is positive for infection, other lesions of the kidney and urinary tract need to be found out.
There is a set of diseases called glomerulonephritis which leads to passage of blood in urine.
Thus, kidney function tests need to be done.
Thanks and take care
