blood sugar value puzzle
Hi. I am a new member. Can any one help me out. Around year and
half ago I have been tested for blood sugar levels and the values
were 81 mg/dl(fasting) and 87 mg/dl (pp). Around five months back I
was again tested and the values were 71 mg/dl(fasting) and 75 mg/dl
(pp). Both tests are from different laboratories. Now around four
months back I had to undergo some minor surgery and for that I had to
be empty stomach from the previous night to the morning of surgery.
But I took half cup of tea (with less sugar) at 6:30 a.m. (the day of
surgery) and reached hospital. There my blood was taken at around
9:15 a.m. In the discharge summery doctor has written that random
blood sugar is 91 mg/dl. I am now afraid why this high value has come
even though I had taken only half cup of tea. Though during previous
tests after taking good meals my blood sugar levels (pp) were 87 and
75 mg/dl. Can someone throw some light on it and relieve me of my
anxiety. Is something serious. My father is also a type II diabetic.
Thanks.

Most laboratory Blood Sugar assays administered by hospital
laboratories have a variability of around 10-12%. The net
result of this variability is that if the TRUE value is 100
mg/dL there is no measurable difference between readings of
90-110mg/dL. That error range is for intralaboratory
(within the same lab) analysis. Interlaboratory (between
different labs) tests would demonstrate an even larger
variability.

One minor change, now the Endocrinology section of the
National Academy of Pediatrics considers two successive fbs
readings as diagnostic for diabetes. Likewise there are
normal circadiam rhythms during the night, release of
cortisol, ACTH, glucagon, and epinephrine that effect blood
sugar readings—called the "dawn effect."

Two successive days.

ps, don’t recall if I noted but the number you stated 140
mg/dL used to be correct. Has major insurance, American
Disability Act etc. implications as that increased the
number of diabetics by 10%.

My guess is stress. I can get a 20 point rise in any stressful
situation. If it went back to normal after the surgery, I wouldn’t
worry.

That I would agree with wholeheartedly.
