Only one code was found in TPP, 1022651000000100 There were 8.57m records in 2020, of which 8.52m had a non-zero value., with a mean of 266.3. Very rough IQR 200-300.

Thanks for this Helen - will need input from @HelenCEBM but an immediate question I had was around units, it looks like this is 109/L, but are units collected separately? If not, we might want to check max values and clean the data based on this anyway...

@annaschultze the "PBCL" documentation will have more background on units if useful (i think)
