Did reference ranges for HCT change to 40-54 recently?

[SkyWarn]

I just had labs and my HCT came in at 53.5 Normal. The ref range is 40 - 54. First time I seen that. 50 was always the cut-off in the past. I don't know which lab this urologist used.

Which lab did they use?

Not sure. The numbers are in the patient portal but until the final labs come in (A1C and Ferritin) I cant see the actual report. But I know from the past he usually uses BioReference.
