Can a core needle biopsy be wrong?

The currently used biopsy systems allow for a precise identification of the site of material sampling. Unfortunately, core needle biopsy carries also a risk of false-negative results.

Why is my urine test positive but blood test negative?

The hook effect happens when you have too much hCG in your blood or urine. How is this possible? Well, the high levels of hCG overwhelm the pregnancy test and it doesn’t bond with them correctly or at all. Rather than two lines saying positive, you get one line that incorrectly says negative.
