when someone is in the early stage of diabetes, their pancreas doesn't work as well as it should.
So the person eats food with carbs. The pancreas can't put out enough insulin and so blood sugar goes high, finally though the pancreas catches up and produces enough insulin, but it may overshoot a little. So highs can be followed by 'relative lows'.
This may be the case, which is why we recommend further checking for diabetes.
The American Association of Clinical Endocrinologist guidelines:
● Ac1 = <5.4 % as normal, 5.5-6.4 impaired [prediabetes], 126 mg/dl
Maintaining normal body weight, abstaining from eating sugary foods, eating a low carb diet, and daily 30-60 exercise can help reverse prediabetes.A follow up FPG or an oral glucose tolerance should be used for definitive diagnosis.
My previous post omitted the following
- Fasting plasma glucose [FPG] normal is 60/70-99 mg/dl
- Fasting impaired glucose [prediabetes] is 100-125 mg/dl
- Fasting diabetes >126 mg/dl
A glucose tolerance test is in order. Sounds like your parent does have some indications that could mean diabetes.
However, if it is early lifestyle measures as mentioned above should be very helpful in managing it.
Thanks to both of you for responding! I let her see your answers!
Why would my parent have a low random blood sugar in the afternoon? Does that normally sometimes happen with pre-diabetes?
The reference range of 74-106 is unusual. A low range of 67 mg/dl is not considered low, below 60 is. One can purchase home glucose meters at almost all drug/pharmacy stores including Wal-Mart. Some run as low as $10. It might behoove your parent to test on their own.
Is the reference range supposed to be below 60 to be considered low even for someone who has not been fasting, as my parent was not? I believe it was the hospital lab the doctor used that flagged the 67 as low.
Thanks, Sally, for explaining! My parent is planning to try a low carb diet model and hopefully ask for further testing at a May 29th appointment.
"Is the reference range supposed to be below 60 to be considered low even for someone who has not been fasting, as my parent was not?"
One is supposed to fall "between" the reference ranges, not below or above. Doesn't matter if the patient has been fasting or the test is random [excludes OGTT [oral glucose tolerance test]]. A doctor may perform random glucose 'blood' testing to see if glucose varies widely throughout the day. Healthy peeps do not. HTH
Note- I hope you now know my intent. I'm sorry I misspoke in my post.
I meant to say:
Is the blood sugar supposed to be below 60 to be considered low even for someone who has not been fasting, as my parent was not?
I already was aware a person's lab specimen when measured is supposed to fall within the APPROPRIATELY printed normal reference range (I don't really think the one the lab printed was the right one for a random specimen).
But while you had cited the reference range for a fasting blood sugar test which had the bottom number of the range as 60 and did not at first very specifically apply it to a random blood sugar specimen in a previous post, in a later post, you went on to say 67 is not considered low, hence the clarifying question I asked you.
Earlier on I commented, "Fasting plasma glucose [FPG] normal is 60/70-99 mg/dl". No mention of 'random'. My labs or doctors do not consider 67 as low, borderline, yes, but not low. However, your parent's doctor may feel otherwise. Hence the / between 60/70.
"(I don't really think the one the lab printed was the right one for a random specimen)"
The lab copy should define the type of test. If not ask the doctor and/or contact the lab for an explanation. My hospital has its own lab but sends certain samples to an outside independent lab for analysis. Both can be contacted.
Just spoke w/the supervisor of the hospital lab. She says blood sugar should be back to normal if it's been more than two hours after eating or something like that (which it likely had been for my parent). She says their reference range is established by testing of people in our specific region and is regulated by some official agency or other (I think a state government agency). She claimed through the tech I spoke to prior to her that fasting and random have the same range.
So far, the doctor has left it to other of his staff to report results who do not know the meaning of them all & my parent has not insisted on talking to him on the phone, but is content to wait until a future appointment.
Thanks for updating us. Try asking the lab supervisor if it's possible to mail all future lab results directly to your parents. This way your parent and yourself won't have to rely on a staff member and you also will have a record on hand.
My mom had gotten the first Hga1c, which was higher than 6 by phone, but we didn't find where she wrote it down, but I think it was 6.1.
I think that was done at the lab there in the doctor's office, where they send out to an independent lab.
The next results from the hospital lab, she did get copies of, but not through the mail.
I know I've gotten differing results on a different kind of blood test on the exact same day between the doctor's independent lab and the hospital's ER lab (was advised to go to ER after visit).
If my mom were to think about getting a home blood sugar testing device, what would be the most accurate ones out there?
Per Consumer Reports, the #1 & #2 meters were Accu-Chek Compact Plus and Accu-Chek Aviva. Both run around $20. CR Best Buy went to ReliOn meters [all three of them] sold at Wal-Mart [approx $10] with annual low cost of test strips approx. $570. Accu-Chek strips came in @ $1700 annually.
Thanks for the consumer report info!
