How low is low and how high is high? 🙂 Still in the laboratory reference range or lower/higher?
It’s not macro—that means big. A low mean cell volume means your cells are small.
On paper, you might have microcytosis (a fancy name for small red blood cells), which could mean you have iron deficiency anaemia. But you’d probably need more tests to be sure.
Low MCV means that RBC are smaller than normal and may indicate microcytic anemia. This condition may be caused by iron deficiency, lead poisoning, or thalassemia, a genetic condition that causes your body to have less hemoglobin than normal.
Hi...thank you for your reply. It doesn't look like they did a full anemia panel which I thought the nurse said they were doing. They did do vitamin D, folate & B12 ( last tested in June was serum b12 & this was 385)
With serum B12 result below 500, (Or active B12 below 70) recommended to be taking a separate B12 supplement
A week later add a separate vitamin B Complex
Then once your serum B12 is over 500 (or Active B12 level has reached 70), you may be able to reduce then stop the B12 and just carry on with the B Complex.
If Vegetarian or vegan likely to need ongoing separate B12 few times a week
Igennus B complex popular option. Nice small tablets. Most people only find they need one per day. But a few people find it’s not high enough dose and may need separate methyl folate couple times a week
Thorne Basic B recommended vitamin B complex that contains folate, but they are large capsules. (You can tip powder out if can’t swallow capsule) Thorne can be difficult to find at reasonable price, should be around £20-£25. iherb.com often have in stock. Or try ebay
IMPORTANT......If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 5-7 days before ALL BLOOD TESTS , as biotin can falsely affect test results
In week before blood test, when you stop vitamin B complex, you might want to consider taking a separate folate supplement (eg Jarrow methyl folate 400mcg) and continue separate B12
Post discussing how biotin can affect test results
Forgot to say just testing TSH is completely inadequate
How much levothyroxine are you taking When were
Approx how much do you weigh in kilo
Many, many members on levothyroxine find when adequately treated TSH will be around or below 1
ESSENTIAL to test TSH, Ft4 and Ft3 together
Recommended that all thyroid blood tests early morning, ideally just before 9am, only drink water between waking and test and last dose levothyroxine 24 hours before test
This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)
Private tests are available as NHS currently rarely tests Ft3 or all relevant vitamins
If you normally take levothyroxine at bedtime/in night ...adjust timings as follows prior to blood test
If testing Monday morning, delay Saturday evening dose levothyroxine until Sunday morning. Delay Sunday evening dose levothyroxine until after blood test on Monday morning. Take Monday evening dose levothyroxine as per normal
Monitor My Health (NHS private test service) offer thyroid and vitamin testing, plus cholesterol and HBA1C for £65
