QIAGEN is a company that helps detect diseases and it supports new guidelines from the American Academy of Pediatrics (AAP) for testing children and teenagers for tuberculosis (TB), which is a serious lung infection. The new guidelines recommend using a test called QFT-Plus, which is better than an older test called TST. This helps find people who have TB without making them sick or uncomfortable. Read from source...

- The headline does not match the content of the article. It implies that QIAGEN supports new AAP guidelines, but the article only mentions that they back the existing QFT-Plus test, which is already supported by the AAP.
- The article contains vague and misleading statements, such as "equently exposed to settings with a higher risk for TB transmission". What does this mean? How often are these children exposed? How high is the risk compared to other factors?
- The article uses emotional language, such as "expanding the role of latent TB screening in national tuberculosis control efforts", which sounds like a call to action or a moral imperative rather than an objective description of a scientific process.
- The article does not provide any evidence or data to support its claims, such as why QFT-Plus is superior to TST, how effective it is, what are the advantages and disadvantages, etc. It relies on unsubstantiated opinions from organizations that have a vested interest in promoting QFT-Plus, such as QIAGEN, AAP, CDC, etc.
- The article does not address any potential challenges, limitations, criticisms, or alternative perspectives on the use of QFT-Plus or TST for TB screening, such as cost, availability, accuracy, safety, ethical issues, etc. It presents a one-sided and uncritical view of the topic.

Positive
Reasoning:
- QIAGEN backs new AAP guidelines supporting QFT-Plus Test, which is a superior alternative to the dated TST for detecting TB infection.
- The updated childhood TB screening guidelines come as U.S. authorities are expanding the role of latent TB screening in national tuberculosis control efforts.
- QIAGEN recently partnered with the International Panel Physicians Association to support and educate panel physicians worldwide on new US CDC tuberculosis screening guidelines that require the use of IGRA tests to ensure a safe immigration process, supporting the global fight against TB.
