One possible reason for a negative urine test and positive blood test could be the difference in sensitivity of the two tests. Urine tests may not detect certain substances or conditions as early or accurately as blood tests.

Another instance could be in some diseases where the concentration of biomarkers is too low in urine to be detected but sufficient in blood.
One cause could be the time factor. Some substances are detected in the blood earlier than in the urine. For example, if a new disease marker is emerging in the body, the blood circulation will carry it first, and it might take a while for it to be excreted into the urine in sufficient amounts to be detected. So, at the time of testing, the blood test shows positive while the urine test is negative.
