Zrt Thyroid Blood Spot Tests

Tvc Offers The Option To Have Your Thyroid Hormone Levels Tested In The Comfort Of Your Own Home

A Woman’s Journey: Thyroid Disease – Often a Surprising Diagnosis

For the convenience of our patients, TVC offers the option to have your thyroid hormone levels tested in the comfort of your own home via dried blood spot through our partnership with ZRT Laboratory. These kits allow patients to collect their sample in the comfort of their own home at a time that suits them.

Dried blood spot is a form of collection where patients place blood drops on a filter card after a finger prick with a lancet. Once dry, blood spot cards are extremely stable for shipment and storage, and the dried blood format offers excellent correlation with serum tests.

Blood spot is a convenient alternative for measuring thyroid hormone levels, and in fact offers distinct advantages over serum testing because it eliminates the need for a blood draw saving patients time and money. No more needles and syringes and no need for an office visit!

Our friends at ZRT Laboratory, who developed the science for accurately measuring thyroid hormones via dried blood spot, worked with TVC to develop custom kits for our patients.

TVC home test kits offer testing for Thyroid Stimulating Hormone , Thyroxine , Triiodothyronine , and Thyroid Peroxidase Antibodies .

Your TVC clinician will recommend for you one of the following six kits :

  • Kit #1 TSH $65.00
  • Kit #2 TSH + free T4 $95.00
  • Kit #3 TSH + free T4 + TPO Ab $125.00
  • Kit #4 TSH + TPO Ab $95.00
  • Kit #5 TSH + free T4 + free T3 $125.00
  • Kit #6 TSH + free T4 + free T3 + TPO Ab $155.00

Capillary Blood Spot Testing

Capillary Blood Spot Testing offers easy alternative to venous blood draws in the laboratory or doctors office.

Blood Spot testing is the future of hormone testing. The process requires only whole capillary blood from a nearly painless finger prick and several tests can be run from a single sample. Blood spot testing provides results on a par with those from serum tests but without the cost and inconvenience of conventional blood drawing. In addition, collection times can be optimized for fasting baseline hormone levels and assessment of HRT dosing and diurnal hormone testing.

Tests offered in the Blood Spot Profiles include:

  • Thyroxine , free

Test Kits Available For Serum Testing:

  • Female serum hormones
  • Methylation and memory
  • ZRT test kits are convenient for patients that are already supplementing with hormone therapy or taking medications. The profiles have ranges adjusted for age, menstrual status, and supplementation types.

    Zrt Free T4 Blood Spot Test

    Free T4 affects tissue function in the body, while bound T4 does not. This test is often used in congunction with TSH testing to measure the extent of hyper- or hypothyroidism.

    Thyroxine is the main hormone produced by the thyroid. Total T4 measures the overall level of T4 output by the thyroid gland.

    Most of the thyroxine in the blood is attached to a protein called thyroxine-binding globulin. Less than 1% of the T4 is unattached. A measures both bound and free thyroxine. Free thyroxine affects tissue function in the body, but bound thyroxine does not.

    A total T4 or free T4 test is primarily ordered in response to an abnormal TSH test result. Sometimes the T4 will be ordered along with a TSH to give the doctor a more complete evaluation of the adequacy of the thyroid hormone feedback system.

    Levels of free T4 in hypothyroidism may remain within normal range for a period of time while total T4 levels are low in the body’s attempt to maintain homeostasis. So, a hypothyroid diagnosis could be delayed if only free T4 is being looked at. These tests are usually ordered when a person has symptoms of hyperthyroidism or hypothyroidism.

    Thyroxine is the predominant hormone produced by the thyroid gland. It is an inactive prohormone, which converts to triiodothyronine within cells.

    Zrt Tsh Blood Spot Test

    ZRT Thyroid Stimulating Hormone (TSH) Blood Spot Home Thyroid Testing ...

    TSH helps regulate the thyroid gland. It is produced by the pituitary gland in response to thyroid hormone levels in the bloodstream. A high level of TSH means not enough thyroid hormone production, and low TSH indicates too much thyroid activity.

    Why Test Total TSH?

    The TSH test measures the levels of TSH, a hormone that is made and released by your pituitary gland. Your pituitary can sense whether there is enough thyroid hormone in the bloodstream, and it releases TSH when it detects insufficient thyroid hormone.

    The TSH is essentially telling your thyroid to “release more hormone.” This is why your TSH rises when your thyroid is underactive. A high TSH means that the pituitary gland is releasing its hormone to try to get the thyroid to respond and produce more thyroid hormone. Conversely, when the pituitary senses that there is too much thyroid hormone circulating, then it slows down or even stops releasing TSH. The lowering of TSH means that the thyroid is no longer getting the message to release hormone, and thyroid hormone production will slow down.

    You’ve Got Options: Thyroid Self

    First, let’s clarify the two ways you can order your own thyroid tests. The first is called “direct-to-consumer” or DTC testing. With this type of testing, you set up an online account with a DTC service provider. You can then select and pay for the laboratory tests you want. You print a lab slip and take it to a local laboratory collection facility for blood collection. Test results are then delivered to you electronically via a secure portal.

    “Home” thyroid tests are typically fingerstick bloodspot tests. After ordering and paying for a test, the collection kit is mailed to you. After you prick your finger with a lancet, you apply the blood to a special filter card, and send the collection kit back to the lab. Again, test results are then delivered to you electronically via a secure portal.

    Both types of testing offer you access to popular thyroid blood tests including thyroid stimulating hormone , free thyroxine ,, and .

    The Pros Of Being Proactive

    Because of the nature of today’s healthcare, many patients have been forced to become proactive medical consumers. You may be unable to get certain tests when you ask for them. Your HMO or health insurer may deny coverage for certain tests. Or you may come up against an overreliance on the thyroid stimulating hormone test. Some doctors use only this test to diagnose or manage thyroid disease. They won’t test for autoimmune thyroid antibodies, actual thyroid hormone levels such as Free T4 and Free T3, or complicating factors such as elevated reverse T3. Getting tested yourself can be a starting point for a discussion, and it’s pretty easy to do:

    • To order DTC or bloodspot tests, you don’t need to first visit your doctor, or have your doctor order the tests.

    • Younot your doctorget to decide which tests you will get.

    • The results are private and are delivered only to you. They do not go to your doctor, health maintenance organization , or health insurer.

    • Your results often include added, easy-to-understand descriptions of the findings and implications, as well as recommended other resources for reading.

    For home bloodspot testing:

    • You don’t need to leave home.

    • You dont need a blood draw .

    • The cost is often less than DTC or conventional lab testing.

    Hormone Balance: The Key To Health

    Most hormones are produced by a group of glands known collectively as the endocrine system. Even though these glands are located in various parts of the body, they are considered one system because of their similar functions and relationship to each other.

    Hormones are secreted into the bloodstream by these glands. From there, they travel to all parts of the body playing the role of chemical messengers turning specific target tissues on or off. Because they cant be stored in the cells, hormones do their work as they pass through and then theyre gone. As a result, hormones must be made and released at the precise time theyre needed. To keep things functioning at their best, the body must constantly fine-tune hormone release to keep levels within proper limits.

    Because of the complexity of these interactions, a hormonal imbalance rarely stems from only one type of hormone. More often, the problem involves a series of hormones that are out of balance. In addition, a disruption in the balance of hormones produced by one gland or set of glands can cause other glands or systems to dysfunction. Before you know it, youre feeling miserable on multiple fronts.

    What You Need To Watch Out For

    Costs: Health insurance rarely covers the cost of home bloodspot testing, and only some insurers reimburse all or part of DTC testing. In most cases, the costs can, however, be paid from flexible spending and health savings accounts

    Overlooking or misinterpreting errors in your test results: A 2017 article in the Annals of Clinical and Laboratory Research explained that even under the best of circumstances, test results can have errors. Physicians may be able to detect those mistakes and make the necessary adjustments in diagnosis. Consumers, on the other hand, may not have that same level of knowledge and could make decisions based on incorrect information. Health conditions can worsenor be overlookedas a result.

    Poor healthcare decisions: Some patients may decide on their own to increase or decrease the dosage of prescribed medications, or stop treatments all together, based on test results. Experts caution against making these types of healthcare decisions without first consulting your healthcare provider and having confirmatory testing.”The tests are reliable and use the exact same testing labs that I use, so I have no problem using the test results,” says integrative physician David Borenstein, M.D., founder of Manhattan Integrative Medicine in New York City. “However, I’ve had patients order thousands of dollars of tests that turned out to be unrelated and completely unnecessary.”

    Thyroid Nodules: Causes, Symptoms & Treatments | Dr. Kannan

    If your M.D. is reluctant to accept your DTC lab test results, ask for an explanation of his or her concerns. Brady Hurst, clinical director of the direct-to-consumer laboratory also recommends that you show the doctor that your results are coming from labs they already use such as LabCorp and Quest Diagnostics. According to Hurst: Doctors may need to have it pointed out that the results would be no different if they ordered the test vs. you ordering the test.

    If the push back centers on function test results, show them that the lab is CLIA-certified and bring in any research that is available on the tests. Most labs have these documents to share, he says.

    Ultimately, though, if your doctor is completely opposed to self-testing, or refuses to consider valid test results, it’s time to find a new provider.

    How Self

    DTC lab testing is almost identical to conventional lab testing. Direct-to-consumer testing services use the same laboratories most doctors uselike LabCorp and Questand the test process and results are identical to those ordered by your doctor. There are two differences, however. First, instead of your doctor ordering the tests, you choose them yourself. Second, the results go directly to you, not your doctor.

    Home bloodspot testing is somewhat different. There is no blood draw. Instead, the fingerprick blood is processed, and results are sent electronically or by mail.

    When done by a reputable provider, bloodspot testing results are considered highly accurate, and the results correlate well with traditional laboratory blood tests.
