Question 1

normal range t3/t4 but extremely low tsh(high sensitivity). slightly low before pregnancy and now extremely low 11 weeks. endocrine dr not concerned?

Accepted Answer

Low TSH: agree not to worry, your hormone levels are fine and the TSH being slightly is because you are pregnant, just like other things that change with pregnancy.
Don't worry.

Question 2

what can cause a false high tsh?

Accepted Answer

Not much: Any lab can have a temporary problems doing any test accurately.  That is why an abnormal level should always be repeated to verify it.  There are temporary causes for high TSH (resolving subacute thyroiditis), so that a 2nd TSH level done a few weeks after an abnormal one, could be normal.  Subclinical hypothyroidism will have a high TSH with other thyroid levels normal, no symptoms.

Question 3

what is high tsh, 3rd generation?

Accepted Answer

Same as others: The 3d generation TSH assays are best at the lowest ranges - the upper range is debatable as tsh, unlike most products in the blood is not distributed in populations in a bell curve.
The upper limits of the "normal" range of 4 to 5 in assays of all generations is probably wrong.

Question 4

what does high tsh 3rd generation level means?

Accepted Answer

Hypothyroidism: Typically it means that you have an underactive thyroid and may need replacement.

Question 5

does high tsh cause low amh?

Accepted Answer

No: The two could happen together but they are not directly related to one another.

Question 6

what is considered a high tsh level?

Accepted Answer

Above 4.5: In most labs, a value above 4.5 is high.  However, symptoms related to low thyroid correlate much better with free T4 levels, rather than tsh.  There are many people with elevated tsh, normal free t4, who feel perfectly normal (subclinical hypothyroidism).  Persistently high TSH levels is indicative of a failing thyroid.

Question 7

what is a dangerously high tsh level?

Accepted Answer

Hypothyroidism: The actual thyroid hormone is T4 and t3 (liothyronine). When they are low, TSH elevates, but how high is somewhat variable, and "high tsh" per se is not dangerous.  A low t4/t3 (liothyronine) can be dangerous; TSH is a good marker of thyroid function, but often it is necessary to measure ft4 or t3 (liothyronine).  A mild elevation of TSH (eg. 4-10) is often without any symptoms and a normal ft4.

Question 8

what are the symptoms of high tsh level?

Accepted Answer

High tsh has no : Symptoms, but indicates hypothyroidis, which can cause fatigue increased sensitivity to cold constipation dry skin unexplained weight gain puffy face hoarseness muscle weakness elevated blood cholesterol level muscle aches, tenderness and stiffness pain, stiffness or swelling in your joints heavier than normal or irregular menstrual periods thinning hair slowed heart rate depression impaired memor.

Question 9

what can i do to lose weight if i have high tsh levels?

Accepted Answer

High TSH: Ask your doctor to correct your thyroid abnormality with medication.  There is no substitute, however, for eating right and exercising.

Question 10

Accepted Answer

: An elevated TSH the vast majority of the time is caused by hypothyroidism, which is an underactive thyroid. Untreated under active thyroid can lead to serious consequences including congestive heart failure depression fatigue and death.
