I’m taking Eltroxin 100/125 every other night..only started on this brand 6 weeks ago as I was getting different ones every 2 months.. 2nd I started getting a dry month and burning at the tip of my tongue
Yes I have Hashimotos..
The endo has said she want me to optimise my Levothyroxine and I. The next sentence said if we increase your Levothyroxine my TSH may become suppressed..
I was 1st diagnosed in 1991 stopped meds after 6 months as I felt worse..
Started again in 2003 never felt any better.. it’s taken all this time to see an endocrinologist.. so I’m desperate.. I’ve just requested what were my low cortisol levels..
I paid for medichecks last summer for levels and have been supplementing since..
I take Viridian B12 B complex it has 200ug of biotin I would have taken it 24 hours before my test would that amount make much difference?clearly it was an oversight by me..
I take my Levothyroxine during the night to optimise absorption..
Instead that week take daily folate and separate B12
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
last test ….was last dose levothyroxine 12 hours before test or 36 hours before test
Serum ferritin level is the biochemical test, which most reliably correlates with relative total body iron stores. In all people, a serum ferritin level of less than 30 micrograms/L confirms the diagnosis of iron deficiency.
Never supplement iron without doing full iron panel test for anaemia first and retest 3-4 times a year if self supplementing.
It’s possible to have low ferritin but high iron
Test early morning, only water to drink between waking and test. Avoid high iron rich dinner night before test
Eating iron rich foods like liver or liver pate once a week plus other red meat, pumpkin seeds and dark chocolate, plus daily orange juice or other vitamin C rich drink can help improve iron absorption
This is interesting because I have noticed that many patients with Hashimoto’s disease and hypothyroidism, start to feel worse when their ferritin drops below 80 and usually there is hair loss when it drops below 50.
Thank you for your incredible patience while you have been awaiting the outcome of our ferritin reference range review. We conducted this with Inuvi lab, which has now changed the reference ranges to the following:
Females 18 ≤ age < 40. 30 to 180
Females 40 ≤ age < 50. 30 to 207
Females 50 ≤ age < 60. 30 to 264l
Females Age ≥ 60. 30 to 332
Males 18 ≤ age < 40 30 to 442
Males Age ≥ 40 30 to 518
The lower limits of 30 are by the NICE threshold of <30 for iron deficiency. Our review of Medichecks data has determined the upper limits. This retrospective study used a large dataset of blood test results from 25,425 healthy participants aged 18 to 97 over seven years. This is the most extensive study on ferritin reference ranges, and we hope to achieve journal publication so that these ranges can be applied more widely.
