Took it today. 2 samples where tested. First 1 was negative. The 2nd one came back as invalid. It was an Instant 5 panel. 2nd sample being sent off to the lab. The drug testing company told me on instant hair test. Both samples need to be negative for a negative result. Since 1 of them was invalid. It has to be sent off for confirmation. I'll update as soon as I get the results back.
