5) P Mean[+ or -]SD: mean[+ or -]standard deviation; RBCFL: red blood cell folate
level Table 2.
The data documented as folate was not serum folate, but rather raw data used to derive red blood cell folate
The researchers also found that nearly a third of the depressed participants from the study had red blood cell folate
levels below normal, and half of these participants had homocysteine levels higher than levels of the two control groups.
Folate deficiency (serum folate 4 ng/mL or red blood cell folate
< 151 ng/mL) and vitamin B12 deficiency (plasma vitamin B12 < 203 pg/mL) were obtained as a national prevalence.
Plot of geometric mean (95% CI) plasma and red blood cell folate
(nmol/L) by treatment group and time in the first phase and second phase of the trial.
women of childbearing age who are at possible increased risk of a neural tube defect-affected pregnancy due to suboptimal red blood cell folate
concentrations, National Health and Nutrition Examination Survey 2007-2012.
Red blood cell folate
concentrations increase more after supplementation with [6S]-5-methyltetrahydrofolate than with folic acid in women of childbearing age.
Low levels of serum and red blood cell folate
are linked to severe symptoms of depression and some patients are less likely to respond to antidepressants.
For the study, red blood cell folate
concentrations were examined in 5248 Canadians aged 6 to 79 years.
The AIA-Pack RBC Folate assay is designed for the quantitative measurement of red blood cell folate
(RBC folate) in whole-blood (heparin or EDTA) samples on Tosoh AIA system analyzers.
Serum vitamin B12, red blood cell folate
and hemoglobin electrophoresis all gave results within normal limits.
Using data from 3 years (1997, 2000, and 2004), we examined results of laboratory tests for red blood cell folate
ordered at 3 hospitals that predominately service the needs of indigent patients.
