Is my estradiol level safe?

Copied directly from my results pdf:

ESTRADIOL,ULTRASENSITIVE, LC/MS 2942 H Reference Range: < OR = 29 pg/mL

TESTOSTERONE, TOTAL, MALES (ADULT), IA 14 L Reference Range: 250-827 ng/dL

I hadn't had my levels taken in over half a year and had been kinda pushing my dosage a bit. I've been taking 0.75ml of 40mg/ml estradiol valerate subcutaneously once a week for a couple months now, my prescription was for 0.5ml a week which i had been on for a few months and never checked my levels. Took the test at the end of the 3rd day of the week so right in the middle between injections. Do the H and L after the result value just mean high and low or is it a different scale of measurement than pg/ml which the reference is shown in?

The only reason i ask about safety is because 2942 seems like a much larger value than anything i have seen around here before but also i don't think I've had an ultrasensitive test before either or if that was the right one to get, so i don't know if this is just a bigger number because the results are measured in smaller incremements. I feel totally fine and physical changes are progressing at a nice rate.
