Huh? Do you know what this smear test phrase means?

[linspins]

I had a smear test back in February, and have been chasing the result recently but doctors phoneline always busy.
This morning I got a letter inviting me for a smear....so I have been phoning lots today to find out my result.
Doctors hadn’t had any info through for me, so they contacted hospital, who said “the smear test contained another persons demographic” and to wait three months and do it again.
Huh? What does that mean? Doctors receptionist didn’t know. Does it mean the sample got contaminated by someone else’s...but then why wait three months to retest?
Any Ideas!

I guess it means they ballsed it up and the sample is contaminated or mislabelled.

I wonder if it means there are different normal thresholds for different age groups. They've checked yours against the wrong age group which means it might be incorrect. I don't know why they couldn't just recheck it against the right one in this case, though! So I might be completely off the mark here.

because they need to wait 3 months to get the right cells again . They swiped the ones they needed (and lost them or whatever...) so they can't do the test again so soon.

There is no difference with age groups

I flippin’ hate smear tests, but now I need to book another! Bother. Better do it though...
Doctors admin also told me that although they have no record of being notified, the hospital apparently send them this message back in March. In the light if the recent breast screening scandal, I’m not filled with confidence right now. 🤨

Means either the original sample had the wrong details on it or some element of inputting those details had gone wrong in the lab (name/dob/NHS number or something) - it's nothing to do with the results or anything medical. They have to get a repeat sample so they know it's definitely you they're reporting on.

It generally means the practice sent your sample in with someone else's details on it. It's not safe to process the sample because you can't be certain who it belongs to. The lab usually sends a rejection letter notifying the sample taker of the issue. They should have contacted you to explain this.
If the lab had input some details incorrectly into the system, you still have the request form and sample pot to compare it to to rectify the error so it is more likely to be at the practice end.

Sorry you have to go through it again.
The sample taker should ask you to check the details on the request form to verify it's correct. They should label the sample pot with at least three demographic identifiers. They should avoid having more than one sample pot out at a time, particularly unlabelled ones.

I’ve taken a ladies smear before and had it come back with this - her address on the computer system was different to what was on the form which is printed from a different system.. so it comes back and has to be repeated
