I just got the test result for methylmalonic acid in urine:
Creatinine: 1.78 g/l
MMA: 2.6 mg/g creatinine
Since I only see MMA mentioned in nmol/l everywhere, I was wondering if I could convert it to that: 2.6 mg/g * 1.78 g/l = 4.6 mg/l MMA. The molecular weight of MMA is 118.091 g/mol, so 0.0046g/(118.091g/mol) ≈ 3.8*10^-5 mol = 38000 nmol. So my MMA would be 38000 nmol/l, which is obviously wrong. Is it even meaningful to convert from mg/g creatine to nmol/l?

Hi, thanks for the explanation. Are you sure you're calculating mmol/mol and not mmol/mmol? Because the creatine is 0.016 mol, so you'd get 0.045mmol/0.016 mol = 2.8mmol/mol right? Still within range.
Also, is taking B12 pointless with these values? My B12 was 152 pmol/l so I felt like I should be taking extra B12 since I believed I was getting some symptoms, but with these MMA results I guess there's no need? I also have low B6 (18nmol/l, should be 30+) and somewhat low folate (9.1 nmol/l).
