Why did I get two positive pregnancy test at home and blood tested negative? How is that possible?

Why did I get two positive pregnancy test at home and blood tested negative? How is that possible?

Different thresholds: It is possible to have positive urine and negative blood. The home urine tests are pretty sensitive- namely they don't miss much.

Is it possible to get the results of a blood pregnancy test in less that 20 min. Or does it take longer to process?
