Urine Dipstick Tests & vitamin C

[Dobbiedoo]

I'm due to take a repeat urine dipstick test due to previous trace of blood. Since the last test I've been taking vitamin C tablets. I've now read these can cause false negative results! I've stopped taking them but wondered how long I should wait before taking the test to ensure it's not affecting my urine? Can't find the answer anywhere online.

Thanks

Clearly this is not a well known thing! I dropped a sample to my GP anyway with a note asking this question and informing them I'd not taken vitamin c for nearly a week, asking them to confirm if ok. I got a weird text back saying that vitamin c may cause kidney stones if taken in high doses (nothing about it affecting results) and to drop them a sample in the next week or so (no acknowledgement of the sample enclosed with the note). As it wasn't clear what they'd done with the sample I dropped, I called them. Receptionist couldn't see any record on computer so, after placing me on hold, came back saying sample had been sent to lab for testing as dipstick abnormal (didn't say why but assuming blood again). Said GP still wanted me to drop second sample next week "because of the vitamin C". Makes no sense as they'd already inferred it wouldn't affect results?! Said she didn't know how long results would be but I'd only hear if anything wrong. This was 4 days ago and now it's the weekend.

Can anyone make sense of this? Anyone had traces of blood and it turned out to be nothing? Needless to say I'm terrified.

Just that really. Waiting for lab results after 2nd abnormal dipstick. Over 50 and no uti symptoms. Very worried. Thanks.
