I doubt you are toxic in B6. This is a very uncommon condition and only manifests when people take very high doses every day for months and years. 5mg a day is not high. It is generally accepted that over 100mg a day (and typically more) may increase risk of toxicity over time. If you have normal kidney functions, a water soluble vitamin is lost when in excess thru the urine.
Most of the cases published resulted initially from treatment of PMS syndrome with 500mg a day for years.
Did you get your B12 measured at the same time? Do you know that result? Folate?
If you took your vitamins on the day before and day of the test, your reading may show higher than the range. The ranges were developed from "normals" who DO NOT TAKE any vitamins. So naturally if you consume B6 in food, and/or a supplement you would expect to be out of range. This is not a "high" like a drug level high or disease state high.
Why did you have the test run in the first place?
A MTHFR mutation would involve methylation of B12 and folate failures.
B6 may flood the serum if the red cells burst when the sample is taken. (this happens with potassium tests too, which may show a false elevation from red cell ruptures).
Secondly you may show high if the lab tested wrong. This is common with tests that are not done routinely. Calibration of the machine may be off, due to a degraded standard sample.
For example, Quest labs in the US had TWO false calibrations over years, for Vit D...and published that fact. They did not follow proper protocols for accurate calibration of the machines.
So your test may be a lab error. It is more common than you think.
You can stop all fortified foods (like cereals, energy drinks, etc) for a while ..stop all vitamins containing B6 or complexes, and then get retested in a 3 months. B6 is stored for a short time in muscle as pyridoxal, but in 3 months most of that would be gone. Just about every person who comes here thinking they are "high" in B6, retests in the normal range later.
Just between you and me...your first post has a typo in it, so I am not going to reply to it. Your reported test result was a huge typo.

Here is a blurb from a good source about too much B6...
Quote:
Can vitamin B6 be harmful?
People almost never get too much vitamin B6 from food. But taking high levels of vitamin B6 from supplements for a year or longer can cause severe nerve damage, leading people to lose control of their bodily movements. The symptoms usually stop when they stop taking the supplements. Other symptoms of too much vitamin B6 include painful, unsightly skin patches, extreme sensitivity to sunlight, nausea, and heartburn.
The upper limits for vitamin B6 are listed below. These levels do not apply to people who are taking vitamin B6 for medical reasons under the care of a doctor.
Life Stage Upper Limit
Birth to 12 months Not established
Children 1–3 years 30 mg
Children 4–8 years 40 mg
Children 9–13 years 60 mg
Teens 14–18 years 80 mg
Adults 100 mg

I wouldn't worry about your reading at this time, therefore.
Very low B6 levels, can cause neuropathies too, and that is why some doctors test for it.
What are you doing for your MTHFR mutation? This mutation is far more critical for you at this time.
