| Video Discription | Are you trying to understand what's going on with your thyroid. Maybe you're asking the question, what is a normal thyroid function test? What are the actual tests that are included and what are the normal values for these tests? In this video we're gonna go into those specific details. We look at some of the tests included in a normal thyroid function test and more expanded thyroid function test. What some of the reference ranges are, and what some of the optimal levels are. So what is a normal thyroid function test? Well, normal can mean a few different things. There can be a base level of thyroid testing and in a more expanded level of thyroid function testing. In this video, we look at both, the basic level of thyroid testing and the more expanded level of thyroid testing. We also discuss what some of the reference ranges are for these tests and maybe even the optimal ranges for some of these tests. but before we dive into that, I want you to keep in mind that while these are very helpful diagnostic tools, there's always contextual things that can sway our understanding or diagnosis in a different direction, separate from what the lab is actually suggest. And this context is sometimes even more important than the lab itself. We always say treat the person, not the lab test. So let's look at some of these basic normal thyroid function tests. The most basic and common thyroid function testing is the TSH and t4. T4 is also known as thyroxine. So for the tsh, the usual reference range is 0.45 to 4.5, and the TSH is coming from your brain, and when that TSH is above 2.5, it is abnormal. TSH is stimulating the thyroid gland to produce that t4. So when that TSH is above 2.5, that is a suggestion that there may be something going on because the brain is not getting that feedback that it needs to lower that tsh. So the reference range, again being around 0.4 to 4.5. So 2.5 is when we start to scrutinize things, more closely, and you may wanna look a little bit closer at the T4 output and see if it's not low. And the T4 reference range is usually gonna be around 0.8 to 1.7 nanograms per deciliter. So , when your TSH is above 2.5, a lot of times. There can be a natural low T4 output and. The problem is sometimes if the TSH doesn't reach high enough above that 4.5, then they don't even run the t4. So a lot of, normal or basic thyroid function test is a TSH with a reflex to the t4. But if you don't reach that threshold on the tsh, it doesn't reflex. But you can have normal TSH and an actual low T4. Normal being within the reference range of 0.4 5 2, 4 0.5. So again, when it's 2.5 or higher, we wanna scrutinize the lab values a little bit more and make sure we're using more tests to triangulate where, the things are actually at. So we use multiple data points to triangulate what the picture actually looks like and also, Look and see what you're actually experiencing. And that's some of the context part that I was referring to earlier. Sometimes you only need the TSH and the t4, but other times you need multiple data points to understand the full picture of what's going on. And so that's where you get into more expanded thyroid function testing. So in a more expanded thyroid function testing, we'd also wanna look at things like free T3 and reverse t3, T3 uptake, thyroglobulin, and even thyroid auto antibodies. So the main thing that your thyroid is producing, again, the TSH stimulates the thyroid. It simulates a thyroid to make t4, and then that T4 is gonna be converted into t3, or sometimes it could be turned into reverse t3. So T3 is the actual active form of your thyroid hormone. So if you have plenty of that t3, usually even a low T4 is going to be okay. And the range for that T3 is gonna be around 2.0 to. 4.9 PICOGRAMS per ml. So in a more expanded thyroid panel, you're gonna be looking at all of these numbers and basically trying to understand what the overall output of that T3 is. So obviously when the T3 and the T4 are below, the reference range is given, and the TSHs above that 4.5. These are usually good indicators that you need thyroid hormone replacement therapy. But what about when that TSH is only 3.0 and the TSH is 0.9? HaFy0AESGrg |
