Do I need to redo my blood test?

So basically I recently recieved my blood test at my 3 month mark. Mind you I applied the estrogen gel (0.5mg) 4 hours before I was due to get my blood test. The result came back at 600 p/mol? Should I have applied my gel earlier? Are the results skewed? Do I need to redo my blood test. My T levels are apparently at 1.5
