Why do you want to perform pertussis nuclλ<eic acid testing?

  Pertussis (pertussis) is a highly conε≤&∏tagious acute respiratory diseas>→ πe mainly caused by B. pertussis infection×✘♣ε. The cough gradually worsened, showi∞ ng a typical paroxysmaΩλ'l and spastic cough. At the end of the'÷  cough, a deep and long chicken-‌↔$βlike inspiratory roar appeared, and the tot σ↓♠al number of white blood cells and★♦δ★ lymphocytes increase✔¥πd. Pertussis can cause a series of $↔ ≤serious complications such as pneumonia and♣§ pertussis encephalop✔₽εathy, and endanger the health of newb♦&orns.

  Clinically, bacterial culture an™♥&d serological screening are commonly used to d✔↕etect B. pertussis, €"but the isolation andε♦" cultivation of B. pertussis is diff±αicult and the culture cycle is long. Sero××>∏logical screening has the defects of low sensitivφ₹ity and low specificity, which limits the abo'™εve Clinical application of two€±☆ detection methods for pertussis>α¥σ bacteria. "Expert Consensus on the Di∏•agnosis and Treatment of Chronic ∏<φ$Wet Cough in Chinese Children (2019Ω≈✘ Edition)" proposed "Pertussis β≠PCR detection has high sensitivity and ca≠♦↓₩n be diagnosed early".&nbs≈‍εδp;Therefore, the detection of pertussis nu λcleic acid can detect the cause of cough as early↓♠©δ as possible; accurat÷σely guide the use of an☆>"tibiotics, reduce drug abuse, and reduce c ↑omplications; prevent and control infection e&☆arly.
