Your age?: We need to know your age. Please put it in your public profile. We cannot answer questions from minors. Knowing your country or state helps, too. Age, location, and gender, can affect our answer, since some conditions are more likely in different places or in different age groups. Be honest! You expect if of us, and we expect it of you!

Blood Sugar (Definition)

The blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood of a human or animal. The body naturally tightly regulates blood glucose levels as a part of metabolic homeostasis. Glucose is the primary source of energy for the body's cells, and blood lipids (in the form of fats and oils) are primarily ...Read more

Chest pain on&off. Tested for low iron. Results normal (iron 62, Ferrin 5). However low blood glucose of 56. (did not fast). Age 25, Why low glucose?

Hmm... different lab: Ferritin 5 is awfully low at every lab I've ever seen. Hypoglycemia can occur from medicines, starvation, a LOT of exercise, paradoxically from obesity and insulin insensitivity (so more is put out and the body eventually overreacts to it), elevated insulin levels (very very rare). or. No clear cause (most common and common in your demographic group).

I had a normal blood sugar (72) about a week ago and today I had another test that resulted to high glucose level at 138. I am 12 weeks pregnant.?

Fasting?: Was the 72 fasting and the 138 not fasting? That might explain the discrepancies. Otherwise, your doctor will ask you to do a glucose tolerant test. Just see your doc. He/she will know what to do.

My grandmom is 76 and has an ESR of 45 mm/hr. All other results (hb, wbc count, blood glucose) are normal, should I be concerned?

My grandmom is 76 and has an ESR of 45 mm/hr. All other results (hb, wbc count, blood glucose) are normal, should I be concerned?

No: Sed rate means nothing in isolation, it's often done wrong in any case, and as a pathologist, I think that the value is fine especially in an older lady.

My grandmother is 76 and has an ESR of 45 mm/hr. All other results (hb, WBC count, blood glucose) are normal, should I be concerned?

My grandmother is 76 and has an ESR of 45 mm/hr. All other results (hb, WBC count, blood glucose) are normal, should I be concerned?

Probably not: The ESR rises as we age. As long as she has no other symptoms or other lab testing that are of concern, close follow up may be all she needs at this time.

Kidney disease: What you are describing is stage 3 Kidney disease, but the labs should be repeated along with urine protein level. If you have high blood pressure, it needs to be controlled. There is treatment to prevent or delay worsening, so talk to your doctor!

When testing glucose can I milk the test site if not enough blood or will this cause a false high or low?

When testing glucose can I milk the test site if not enough blood or will this cause a false high or low?

Squeeze away: Whatever it takes to get enough blood to test. This won't affect the result significantly.

Which parts of body can be used to prick for testing blood glucose level?

Which parts of body can be used to prick for testing blood glucose level?

Any: Anyplace where you can get a drop of blood. Avoid the toes if you have diabetes. Remember, sticks other than the fingers will give you what your sugar level was 15 minutes ago, not what it is now.

Are you allowed to take medication or not while testing blood glucose after taking medicine at breakfast?

Are you allowed to take medication or not while testing blood glucose after taking medicine at breakfast?

Please clarify: Hi. I'm confused. For standard diabetes tests (either fasting glucose or a glucose tolerance test) you go in for the test FASTING (i.e., NO BREAKFAST!). I'm not as worried about the meds messing up the test as I am by the fact you ate breakfast! The test is probably invalid. Be sure to tell your doctor who ordered the test. May have to repeat it. Good luck. PS Water is OK before & during test.

After having a uti, finding glucose in my urine, and testing negative for blood sugar problems, I haven't been able to hold urine at times.

Glucose in urine: It is not normal for you to have glucose in your urine. I am not sure what you mean by "testing negative for glucose problems". Have your physician order a hemoglobin a1c test. If it is normal, then you do not have diabetes. Your description of not being able to hold urine, at times is a concern. Have your physician sent you to a urologist to see why you have problems with holding your urine.

What are the best blood glucose results?

What are the best blood glucose results?

Blood sugar levels.: For fasting glucose, up to 100 normal, 101-125 prediabetes and 126 and up diabetes. For A1C, up to 5.6% normal, 5.7-6.4% prediabetes, 6.5% and up consistent with diabetes. Blood sugar should be lower than 140 two hours after eating. This is for someone who isn't diabetic. For diabetics, finger sticks should be 90-135.
