Persistent leukocytes in urine without real UTI infection or problems normal or not?

Asking on behalf of my wife. She never had UTIs before married life, before we started having vaginal penetrative sex. She has since gotten 2 UTIs, this last one while seemingly over (symtoms wise), with the test strips she is still testing faintly/partially positive for leukocytes.

She went to doctor for follow up before and gotten extension on the prescription to kill the UTI bacteria.

We're just wondering is it normal to still have leukocytes detected in urine when she is otherwise fine. Or does this indicate an underlying issue to still resolve? Online research so far hasn't come up with anything useful regarding leukocytes while otherwise healthy.

She's supposedly been "recovered" for about two weeks since she last took the (refill) medications, and another week or two before that for the initial medication from UTI infection. So it's been a while now, and she's still detecting leukocytes.

For medication, she was prescribed Nitrofurantoin (Macrobid).

Hi, they call it Honeymoon Cystitis and it’s quite common at first. The antibiotic she is taking is a good one for a UTI which is commonly caused by the E-Coli bug.

After a while things will settle down, if not they will investigate so no need to worry. Just tell her to make sure that she empties her bladder completely when she spends a penny.

Any old urine left inside can start to build up bacteria which then causes problems.

Edit:

I had to have a second course of antibiotics once when the first course didn’t clear it, but if you are still worried, go back to the doctor.
