Navigating the land The C-Telopeptide (CTX) Blood Test measures CTX levels in the blood Test Code(s):. 500089, 17406. Also Known As: Type 1 Collagen, C-Telopeptide. scape of C Telopeptide (CTx) | Quest laboratory markers can be complex, especially w Collagen Type I C-Telopeptide Test hen you are looking for specific biochemical indicators. In my journey exploring various physiological markers, I have encountered the c telopeptide test code frequently. Whether you are researching bone biology or simply trying to organize your own health data, understanding how these identifiers function is essential.
What Is the C-Telopeptide Test?
At its core, this assessment focuses on Collagen Type I C-Telopeptide, often abbrevia C-Telopeptide, Serum. Test Code: 500089. Performing Lab: LabCorp. CPT Code: 82523 001. Test Link (Copy). Order Information Results. Synonym. Collagen Cross- ted as CTX. It is a byproduct that measures CTX fragments released during bone breakdown. In many research contexts, this is used as a biomarker in the serum to measure the rate of bone turnover.
When I first started looking into this, I was confused by the variety of identifiers. You will see terms like Beta-CrossLaps or Crosslaps, which are essentially synonyms for the same biological entity. Because this marker is sensitive to daily fluctuations, many protocols suggest that an early morning specimen is preferred and that fasting is recommended to ensure the most consistent data.
Deciphering the Test Code and CPT Landscape
If you have ever tried to look up a specific laboratory order, you know that the code system can vary wildly between provi This test may be used as an aid in monitoring bone resorption changes of antiresorptive therapies in postmenopausal women, individuals with osteopenia. ders. A test might be listed under one ID at one facility and a different one elsewhere.
* Common Identifiers: You might encounter Test Code 500089, which is a widely recognized Performing Labcorp Test Code.
* Alternative Labels: Others include Test Code 17406, Test Code LAB2964, Test Code LAB21008, and even Test Code 6557.
* Standardization: The LOINC identifier 41171-0 is often used to standardize these results across different digital systems.
* Billing: When reviewing paperwork, you might see CPT Code 82523, which is frequently associated with the COLLAGEN TYPE 1 C-TELOPEPTIDE (CTx) analysis. For those in a hospital system, you might even see an Orderable EAP code: LAB103292.

Personal Observations on Variability
In my own documentation, I have noticed that the specific C or CTX designation is crucial. For instance, 141093 refers to N-Telopeptide, which is a different fragment entirely, u The Collagen Type I C-Telopeptide (CTX) Test measures CTX fragments released during bone breakdown, making it a key marker of bone resorption. sually collected via urine. It is easy to mix these up if you aren't paying close attention to the Test Code: CTX provided on your specific lab requisition.
When reviewing data, I often look at the TELOPEPTIDE-C or CTELO mnemonics to ensure I am looking at the serum-based Collagen Type I C-Telopeptide rather than a urine-based crosslink test.
Interpreting the Data
When evaluating the levels of collagen type I in the blood, context is everything. I have read discussions suggesting that 100 is too much suppression in certain contexts, while others look for values around 150 as a moderate baseline. Because this measures the level of collagen type I in the blood as a snapshot in time, I have found that looking at trends over several months is far more useful than a single, isolated result.
If you are digging into your own records, keep an eye on the specific Code provided by your lab. Whether it is 3000907 or a custom Epic code, keeping a personal log of these identifiers helps maintain clarity. Always remember that these markers are part of a larger picture of biological health, and tracking them requires patience and attention to detail.
