Question -- wrong result on a blood draw PG test?

[Kathie in Thorp]

I could be imagining this . . . it's possible. I have a vivid imagination.

The heifer we pulled a day-dead calf from last year showed not pregnant on the tail blood draw PG test after we AI'd in the Fall. Have you ever seen one of them wrong, that direction? I swear, the girl looks like she's bag'n up!

Have had false positives, but no false negatives. Of course, we usually shipped most that came up open shortly thereafter...

The blood test gives you a number , that number relates to the "chance"of pg . You can call the lab they'll explain it better.
They are more correct on negatives.

Named'em, that cow tested 42 days post-breeding as "open" -- her response number on the test was 0.0703. Their literature says they are 99.9% accurate for NOT PREGNANT. I trust their data; I might just have a weird cow -- that would be nice!

Can you "bump" her on her right side?

I hope they're wrong!

I had thrm wrong once on opens, it was human error got straightened out no problems the ones actually bred were much better than the actual opens. Only had a couple called bred that never calved they probably lost it along the way.
