607566 tn?1221252380 Thanks for all the input, I just don,t get how she could say I have diabetes from a 126 glucose and I wasn't fasting for the last 2 test. I wasn't sure if the Dr was just a waste of my time diagnosing me on 2 non-fasting results.
194838 tn?1303428544 to get labs done, especially if you have diabetes, they will most likely want to do a cholesterol test, which IS a fasting test. This test will be very good info for keeping up with your overall health. If I were you, I would just skip breakfast or lunch, whatever is closer to your app.
Avatar m tn You should ask your doctor your question. That you had seen elsewhere fasting was needed for the test and what, if any effect on the test result would having eaten prior have. I did find this on the NIH web site “Although FibroTest may be performed on blood samples from fasting or non-fasting patients, FibroMAX must be performed on samples from fasting patients.“ So it looks like it depends on the specific test used.
Avatar n tn Dear pdr7686, Thank you for your kind reply. I have not undergone A1C test yet. I will go for it today itself. Do i need to do fasting for it or anytime i can get it done? Yes my work is stress related, but i am trying to cope up with it by keeping myself calm. at present my BP is normal. Does this A1C test will give conclusive result whether i am diabetic or not?
2129836 tn?1335496608 The HbA1c protocol has been used for many, many years in the United States as a diagnostic screen for diabetes and a screen for persons of high risk.
Avatar f tn Hello~I am not a doctor or lab technician, so I really can not give you a clear answer on this. However, I am wondering if this test was "fasting" or "non-fasting" If fasting, the glucose looks a wee bit high to me, not much, but higher than most doctors like it to be if you are fasting, the desired levels are under 100.
Avatar m tn HI 48 year old male, 5 feet 8 inches. 164 lbs. Recently had blood test , Blood sugar came back 128m/dl. Doctor has not recommended any medicines . He suggested to exercise and control the diet. Day before the test had a pasta lunch with cola and small pasta fried fish dinner with 2 drinks(alcoholic). dinner complete at 9.00pm. Also had a antidepressant for sleep. Went the next morning for test around 8.am. Is it possible for my test to be wrong given the previous days gluttony.
Avatar m tn I am a little concerned over the elevated fasting glucose level, have they drawn an A1C? This will tell what the sugars have been doing for the last 3 months. As to the rest of the test, being I am not an RN or Lab tech, I really can not interpret the numbers.
Avatar m tn As long as you were fasting for the tests, your CMP should not be compromised. You do not need to fast for a CBC and TSH.
490398 tn?1319940717 This is NOT a fasting glucose. My dad is diabetic and he has all of the tools to test blood. He has regular diabetes not Type 2 but it usually skips a generation. I had blood taken at the doctor last week, again, not fasting, for other health problems and it came back at 169. My doc obviously wants to retest me when I've been fasting and get an A1c.
Avatar m tn The Blood Test was Tuesday morning. The results which were flagged as "high" were Hematocrit 52.3%", Glucose 107 mg/dl, Albumin 5.1 g/dl, A/G Ratio 2.7, Bilirubin Total 1.3mg/dl. I don't know what any of this means.
Avatar n tn I have had a blood sugar test and gave a reading of 6.1 about 1 hour after a breakfast (Weetabix, Milk, Orange Juice). I have to go back and have repeat test but after having nothing to eat approx 9 hours beforehand....will this give an increased or decreased reading.
Avatar m tn The obvious question to ask here is did you fast before the test? If fasting is not done, the test results can be all over the place. For one of my tests I looked at the clock and realised I was eating when I shouldn't be. I didn't cancel the test and the results showed my cholesterol was higher than it should be. Ready to increase my Statins, I had to own up to my GP and she was not happy with me :( Another fasting test soon after revealed low cholesterol.
476246 tn?1418870914 Thanks sweetie. I have to go in for blood tests on the 29th and they said the biopsy would be the day after. Luv you too, sis'!
Avatar f tn What is your doctor saying about it? Elevated lymphocytes can indicate a number of things, from infection or inflammation to more serious things, like leukemia. Medications can cause it, too. https://my.clevelandclinic.org/health/diseases/17751-lymphocytosis Your triglycerides are REALLY high, though you weren't fasting. Are they going to do the test again with you fasting? How low are your ferritin and vit D?
Avatar n tn I have only heard fast for my Cholesterol 12 hours only water..Nothing bout Fasting for thyroid blood test, does it make a difference to the test? I Haven't heard dont drink before a test, but i probably wouldn't..
Avatar n tn Lastly, I suggest you see your doctor for an A1c [HbA1c, HgbA1c, HA1c] test. The A1c measures your blood sugars over the past 2-3 months and provides a better idea if you are a diabetes candidate or not. If your doctor verifies diabetes post back to this thread. We can further assist you with diabetic lifestyle changes one has to make in order to better control and manage your blood sugars.
Avatar n tn Fasting isn't a weight loss technique, really. Your weight and leanness is determined by your genetics and by your diet and how it affects your metabolism. Fasting can be useful for spiritual and detoxification, but obviously one doesn't need to detox a whole lot.
Avatar f tn I'm so pissed my doctor sent to do a blood glucose test gave me instructions not to fast and now that I got here the nurse told me I have to fast for it to be correct... like what the f***... has anyone had to take that 3 hours test cause of not fasting??
190885 tn?1333025891 last blood test i got was in june.... i've got a basic blood test set up for tomorrow morning at 9 am...they said don't eat anything 12 hours before the blood test...if i didn't ask about it they wouldn't have told me...so is it important to not eat anything for 12 hours before this basic liver funtion test? thanks...
Avatar n tn I think being it was fasting. (They have me test early b/c my Mom had Gest. Diabetes)......The blood test is generally more accurate than a regular glucometer.....I'm an RN and sometimes we play around and check our own on the hospital units and get different readings every time...one right after another,......
Avatar n tn In general, if your blood sugar level is below 100 mg / dL after fasting for at least 8 to 10 hours, then your blood sugar is normal. Blood sugar levels are usually lowest before each meal.
