new test strips buggy?

Hey all,
I was diagnosed a little over a month ago with T2, immediately began
low-carbing and taking meds and after first week of testing, my numbers dropped
into good range 80-110 and have stayed there ever since.

Just this week I picked up some new test strips which were coded 17 (a number I
didn't have before) I did a control and noticed that the control range was much
higher on this vial than on any I'd had before at 105-142. My first control
test was at the utmost limit 142. I waited a minute and did another control and
that one was in the 120s. I figured they were all right to use but for the past
week my numbers seem to have jumped from previously being always in the 90s to
now always above 110. Then yesterday my fasting bg was 124 according to the
meter and I can't figure out what's going on.

I never previously had the dawn effect, I'm eating the same, I haven't changed
medications, I don't have sick/cold, I've been exercising just as much. Should
I stop worrying because these test strips simply read higher than previous
ones? Or should I treat numbers like the 124 like a real high and eat
accordingly (no carbs for several hours until it comes down)? I realize 124
isn't all that high anyway and I don't want to be accused of micro-managing,
but since I'm still new to this disease I'm trying to figure out how to use
testing and bg readings to my best advantage.
Thanks for any advice.

Tara, the control numbers on the vial have *nothing* to do with blood
glucose ranges - they're merely calibration references for the meter.  When
you do a control test, if the number on the meter is within the range
specified on the vial, then the calibration is correct.

What meter are you using?  Does it need to be calibrated each time you use
it?  I use the Accu-Chek Advantage; there is a code key that comes with
every new box of strips, and the new key must be inserted into the back of
the meter.  If that isn't done, test results will not be accurate.  Also,
the number on the new code key must match the number on the new vial of
strips.

When you got the 124 reading, did you test again to see if that was just a
glitch?  Many times I've retested immediately after getting a too high/too
low number and learned that I had a bad strip on the first test.  Also, I
don't know how old you are, but sometimes the time of month (and menopause,
too!) can make your numbers go a little wacky.  Keep in mind that some
people would *love* to have an FBG of only 124, so while that's a little
high, it's no reason to panic.

When I get a higher fasting BG, I cut back on (not eliminate) the number of
carbs I have for breakfast.  If I cut back too far on the carbs at
breakfast, I run the risk of a hypo by lunchtime because of the Glucotrol
I'm on.

Keep in mind that it can take several weeks for medications to really kick
in and do their job.  Doctors usually start patients on low doses and ramp
them up as needed, so check in with your doctor if you think the meds aren't
working as well as they should.  Give yourself a little time - you may have
numbers all over the place until your body adjusts to the meds and diet.
For peace of mind, you may want to talk to your doctor.  Perhaps he/she can
refer you to a diabetes education class and a dietician.

Hang in there - it sounds like you're off to a great start managing this
disease!

I got a vial of bad test strips once, for my ultrasmart.  I don't test
with control solution every vial, but I realized my results were odd and
did the control solution test.  It was outside the control range, and
again when I repeated the test, so I took the package back to the
pharmacy and they replaced it with another package.  They thought it odd
one package in a batch would be bad, but I figured it could have been on
the corner of the box and gotten hot or cold in shipping.

I've wondered about variations between different lots of strips (within
the control range), but haven't seen much sign of it.  I got a WalMart
meter as backup for traveling out of the country and while it runs 5-10
points lower than my ultrasmart (whole blood rather than plasma reading,
I guess) it is nice to be able to check a weird reading on a different
meter.  The test strips are individually wrapped so they don't have to
be used within a few months after opening.

I'm fairly new to this too, and a couple of days ago had a similar
situation. A new bottle of strips (Freestyle code 17) and suddenly my
numbers were 10-20 points lower than normal. I too used the control solution
and it was within the normal range (but at the low end so I too wondered if
that indicated that this bottle of strips just run lower). In any event,
after a lovely day and a half spent exclusively in the 80's, I switched to a
new bottle of strips and my numbers were back to what I'm used to. I plan on
calling the company, I bet they'll replace the strips free of charge. Get
some new strips and compare.

I think that people expect too much from our meters.  I have
seen a lot of minor problems over the years.  That is the
reason I keep to different meters and if I see any thing
that looks wrong I do a double check on the other meter
If you look for a while you can stumble on a deal.
for the backup.
It saved me from a gross problem in  two cases.
There was one brand meter that would read high for
part of the day then act normal. The problem is I use the
meter to set dose.  Too much insulin---hypo time.
I currently use a Ultra and a Walmart meter.
Mostly Ultra because of it's convenience.  I
switch to use up the backup strips.
The meters are not fool proof but a lot better
than what we had.  Urine strips only told
you if you were dumping sugar (over 150) and
was given +1 to +4 as a reading. I always had
problems with the color strips for blood. You compared
the blood area against a color chart.
The meter require a bit of understanding and experience.
They are not a 1% device but very adequate for the job.
I am looking at other meters because I have trouble handling
the Ultra strips. Doubt if I would be alive without the meters,
No bull.

Try the Accu chek Compact.  It is nice not to have to mess with those
darn sticks.

Thanks Tori, and all others who advised. I just tested tonight about 2 and half
hours after dinner and my bg was 146 (!) and the only carbs I'd had in about
four hours were two small stuffed mushrooms that were about 9 carbs each. I
tested again immediately and the next reading was 118! I tested one more time
and it was 110! I threw this bottle fo strips out and got the other bottle from
the same 50 count package out. I did a control and the control was in range
aroudn 133. I'm giong to keep watching my numbers and if these don't seem to be
working right I'm gonna toss these and just see if i can either refill
prescription or buy new strips with cash.
So aggravating and scary!
Thanks for the advise,
Tara

Strips are expensive enough that you would do better to either return them to
the pharmacy or call the company and have them replaced.  Depending on the
meter you're using, 100 strips may run in the $75-100 range.

Which meter are you using?  Someone can give you more specific instructions
for changing your meter according to the strips.

I use a OneTouch UltraSmart.  Each box of strips comes with a calibration
number.  It might be 2 or 10 or 25.  I have to change the setting on the meter
to match the number on the strips in order to get accurate results.  

You said that you had a new number on your strips, but you didn't say if you
changed the setting on your meter to match the new number.  This is important!

DONT THROW THEM AWAY!

call the manufacture. they WILL replace them
for you free of charge. tell them what problems
you are having, even if it's operator error, Roche
and Lifescan are both good at replacing strips.

I use over 7,000 strips per year in my Ultra and my wife uses about
4,500 and we've never had a vial of "bad" strips yet.  Been using the
Ultra since it first hit the marketplace...  Why throw them out?  IF you
think they are "bad" Lifescan will replace them.

I use an Ultra and have not had any problems with it, except
when I don't wash my hands prior to testing. Sometimes I forget
and sometimes its not practical. Usually its not a problem but
occasionally I get strange numbers and its often something on my
hands. I've actually found that one bottle of store brand orange
colored liquid hand soap has something in it which causes
readings to be 15-20 points higher. Washing my hands with
another brand of clear soap causes the readings to be accurate.

Oops. To all who asked: I use a One Touch Ultra meter. It's never been
problematic before, so I'm pretty sure there's something wrong with the strips.
I don't have a secondary meter but maybe I'll look into getting one. I'm
starting to wonder if the crazy cold weather and my often lacking heat
apartment and office could have thrown either the meter or vial of strips off
whack.

When you changed to the strips with the different number on the vial, did
you change the the number *in* your meter to match?

Tara I believe the higher the reading on the strips from the control,
does increase the readings of your bg.  I try to have them right in the
middle,  Is that cheating?

Sorry all--Yes I definitely changed the calibration on the meter to match the
vial (I should have answered that before). I will try to call Lifescan and see
what they say about replacing the first vial. I've started to use the second
vial from the package and this one seems to be working ok, my numbers have been
under 110 again all day. I'll keep watching it though.
