The answer is that it is not as good as traditional methods, but is probably useful for establishing trends in the hemoglobin concentration. There is some disagreement in the literature... First reference states hemocue is not as accurate as the coox method, second reference more favorable for hemocue.
HERE IS A GOOD REFERENCE FOR YOU
Translated, first reference stated this means that hemocue generally produces numbers that are falsely low, but that the low numbers are probably not significant in most patients. Patients at the extremes of hemoglobin concentration are at risk from having falsely low measurement, but, again, for watching trends of hemoglobin it is probably a decent alternative to the traditional lab.
Second reference does not find these problems.
In short, it depends on why you are using it and the variation from the lab method will not usually be of clinical significance.
I am standing by for your questions if you have any. If this has been a good answer for you then positive feedback is appreciated.
Thank you for all the information. The second article was better for hermocue. I'm anemic so I use the meter quite a bit. It seems to be 96g/L most of the time. How much should I trust the results?
I think the variability versus the lab test would only be of concern if you are severely anemic. It is probably very useful, as mentioned, to establish a trend. In other words, if you see your counts persistently dropping that should prompt a visit to your doctor. If your results over time are stable that is of value as the meter is very accurate, simply not as accurate as the traditional lab measures. Also, if your symptoms of anemia are worsening and your meter is not showing a drop that would also be a reason to check with your physician.
Thanks so much. You've been a big help.
I just got my blood work done and it turned out HGB 113, Hematocrit 31 and RBC 3.64. My meter reads HGB 101g/l. My HGB should be 103 when considering my htc at 31. Does that sound right to you?
so I should go with the 103 rather than the 113?
I can see how the trend are more important. What I meant was if you look at my hematocrit at 31 then my hemoglobin should be 103 which is what I'm now testing at home compared to the lab at 113 which would have a higher hematocrit.
The hgb at 113 would have a hematocrit of 39, but the lab measurement is 31.
I think I understand. Thank you very much.
Hi. I went to see my doctor yesterday and he said the numbers could be way out on the big machines too. My last test I had done at our hospital but usually I go to lifelabs at my clinic. He said to stick to one lab so that the results won't be so confusing. He also said to use my meter between tests as it should be fairly accurate.
excellent. great. hope you have some peace with this issue now.
yes I feel much better. Thanks again for your help!!!
Hi. I just got my lab test results. My RBC was 3.56, hematocrit 30 and hemoglobin 10.1. I tested with my machine just before the lab and it was 10.1 too. Should I be worried?
hi. I was actually more worried about my hemoglobin being 101 but Thank you anyway.
Thanks again. Yes, these numbers make more sense. Lets hope my hemoglobin doesn't get that low. Last year my hemoglobin was really low and I was in the hospital for a week !!!
