Trigger – does hcg break down faster in the blood? | Forum to have children

Hello,
Is anyone familiar with it?
I would be interested in how the hcg breaks down in the blood through the trigger injection. Does it degrade faster than in urine?
I wanted to spare me guessing the lines and do a blood test. But I wonder how long the hcg from the syringe can still be detected in the blood.
The hcg degradation calculator is only for urine.
