New blood test could revolutionize TB treatment monitoring
NCT ID NCT07157904
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study in Kenya will test whether a new blood test, called PATHFAST TB LAM ag, can better track how well tuberculosis (TB) treatment is working. Researchers will follow 300 adults with TB, collecting samples regularly during their 6-month treatment. The goal is to see if changes in a substance called LAM can predict treatment success or failure earlier than current methods.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- PATHFAST TB LAM ag assay (a blood test for LAM, a substance from TB bacteria)
- What this could lead to
- If successful, this test could provide a faster, simpler way to monitor TB treatment, helping doctors catch problems early and improve recovery rates.
- What could go wrong
- This is an early observational study with only 300 participants, so results may not apply to all TB patients. The test's accuracy in real-world settings is still unproven.

Who is studied
To ensure a representative sample reflecting a broad spectrum of TB disease severity and healthcare access, investigators will recruit participants from multiple healthcare facilities at different levels of the Kenyan health system. The primary study sites include Rhodes Chest Clinic (RCC) and Mbagathi County Referral Hospital (MCH). RCC is a Level 2 healthcare facility which serves as a specialized primary care center for TB patients, recording approximately 700-800 new PTB cases every year. MCH is a Level 5 referral hospital offering both outpatient and inpatient care with a bed capacity of around 150. MCH manages 1,000 new TB cases annually.
