What is the normal TSH level for an adult?

Normal TSH levels for the average adult is from 0.4 4.5 mIU/L. mIU/L means milli international units per liter of blood, a measurement unit for tsh 3rd generation normal ranges. TSH normal values from zero to 2.5 is optimal.

What should my TSH level be at 36 weeks?

Goal TSH level for patients on thyroxine is between 0.5 to 2.5 mU/L. TSH Normal Levels chart by age. Normal TSH levels for children For premature birth (newborn 28-36 weeks) is 0.7 27 mIU/L Age 21 54 years is 0.4 4.2 mIU/L. Age 55 87 years is 0.5 8.9 mIU/L Chart of TSH normal levels during pregnancy

What does it mean when your TSH level is too high?

The amount of TSH circulating in your bloodstream indicates how well your thyroid gland is functioning. TSH levels that are too high or too low can tell your doctor if you have a thyroid disorder or not. Learn more about what normal, high and low TSH levels mean.

What’s the standard TSH reading for euthyroid patients?

Currently, the standard reference range for TSH is 0.4 – 3.0 mIU/L. However, clinical data show that 95% of euthyroid patients fall in the range of 0.4 – 2.5 mIU/L.

When is the TSH level above the normal range?

In general, when the TSH level is above the normal range, your TSH level is high. If it is below the normal range, the TSH level is low. For example, an average adult has a normal TSH level ranging from 0.4 – 4.2 mIU/L. If the result is more than 4.2 mIU/L, the TSH level is high.

Currently, the standard reference range for TSH is 0.4 – 3.0 mIU/L. However, clinical data show that 95% of euthyroid patients fall in the range of 0.4 – 2.5 mIU/L.

When to seek medical attention for low TSH?

It is crucial to seek medical attention if you have hypothyroidism and low TSH levels. Your doctor will order additional blood tests or brain scans to detect the underlying cause of the problem. The most common cause of low TSH level is a hyperactive thyroid gland.

Is there a link between TSH and age?

By contrast, the 1977 UK Whickham study comprising 2779 people reported no significant association between TSH and increasing age in men or in women with negative thyroid antibody tests ( 5 ), although this might be explained partly by the use of older, less precise TSH assays.

Who are excluded from the TSH reference intervals?

Cases below 18 years of age were also excluded. We measured TSH distribution among different age groups and by gender. We identified the latest TSH measurements in 153127 people from the reference population after applying the exclusion criteria.

How are age and gender specific TSH measurements calculated?

All statistical analyses were performed using SPSS version 18.0 (SPSS Inc, Chicago, Illinois). The TSH measurements were grouped by 10-year age band, with all those aged older than 90 years grouped into a single band. The means, medians, and percentiles were calculated for each age group and gender.

Can a high TSH level be a sign of thyroid disease?

Due to the symbiotic nature they have with thyroid hormones, TSH levels in the blood can theoretically be a good marker of thyroid health. This TSH levels chart presents a simplified version of what different readings can indicate. Those with Graves’ disease (an overactive thyroid) have high low TSH and subsequent high thyroid hormone levels.
