I got concerned when some forum members reported trigs/HDL ratios which seemed to be wrong, after using the above calculator.
It appeared that it was set up wrongly to compensate twice for the difference in converting US mg/dl readings to UK mmol/L figures.
For those who don't know, US figures of (say) HDL 100 mg/dl and trigs of 100 mg/dl (where HDL and trigs values are the same) DO NOT translate to the same figures in mmol/L
HDL 100 mg/dl is divided by 38.6 to give 2.59 mmol/L
trigs 100 mg/dl is divided by 88.5 to give 1.13 mmol/L
So, when comparing trigs to HDL in the US, HDL figures are 2.29 times bigger. From this stems the recommended US ranges for trigs to HDL ratios being roughly 2.29 times higher than in the UK.
That's the bad news.
The good news is that I contacted Hugh earlier and he has fixed the glitch in his converter. I tested it both before and after his intervention and can confirm it's now working as it should.
SO I CAN NOW FULLY ENDORSE USING THE ABOVE CALCULATOR
A big shout-out to Hugh Chou for his prompt response !
