Triage TB in a single visit. Before the lab, not instead of it.
ParakhTB pairs a urine strip with the SamaClip finger-clip reader to flag, in about a minute, who at a primary health centre should go on for a confirmatory TB test — with no needle, no microscope, and no second visit. It does not diagnose tuberculosis. It decides who needs Xpert.
A urine strip and a fingertip, working together.
ParakhTB runs on the same SamaClip optical reader already used for community screening — no extra lab, no extra machine. One device, one visit, one decision.
Sample and read, in one sitting.
A patient who is symptom-screen positive or contact-traced gives a urine sample and a 60-second finger-clip reading at the same visit. Nothing is sent away; nothing waits for a second appointment.
What the strip sees, and what the clip sees.
The strip reads urinary markers of TB. The same finger-clip reads the vital-sign pattern TB disturbs — breathing rate, heart rate, temperature and haemoglobin. Two independent windows on the same patient.
A single, fused decision.
The device combines both into one call: refer for Xpert, monitor, or no further action. The point is not to label the disease — it is to decide, fast, who should move on to a confirmatory test.
We don't replace Xpert. We decide who needs it.
Confirmatory TB testing — Xpert MTB/RIF, chest imaging — is accurate but scarce, and not everyone with a cough needs it. The gap sits between the symptom screen, which over-refers, and the lab, which can't absorb everyone. That gap is where patients fall out of the cascade.
ParakhTB fills it. A one-minute, single-visit read narrows the symptom-positive crowd down to the people whose urinary markers and disturbed vitals together warrant a confirmatory test — so scarce Xpert capacity goes to the patients most likely to need it.
A triage and referral signal — never a diagnosis.
Two jobs the cascade does badly today.
The children who can't be tested the usual way.
Young children rarely produce the sputum that standard TB testing relies on, so they slip through. A non-invasive urine sample plus a finger-clip read is child-friendly and repeatable — used alongside symptom screening to decide which children move on to confirmatory testing.
Catch a patient who isn't responding, sooner.
TB treatment runs for months. At every DOTS follow-up, the same one-minute read tracks how a patient's vitals and recovery are trending — so someone who isn't responding is flagged earlier, not at the end of a failed course.
ParakhTB is a triage-and-referral tool, not a diagnostic. It does not confirm or rule out tuberculosis. A confirmatory test — Xpert MTB/RIF, culture or chest imaging — remains the standard for diagnosis, and ParakhTB exists to get the right patients there faster. Device-level TB performance is under validation with our clinical partners.
Bring single-visit TB triage to your district.
Whether you run a TB program, fund one, or study one — let's talk about putting a fast, non-invasive triage step in front of scarce confirmatory testing.
India carries roughly a quarter of the world's tuberculosis — more than any other country (WHO Global Tuberculosis Report). ParakhTB is built for exactly this setting: high burden, scarce confirmatory testing, and people who fall out of the cascade between a symptom screen and a lab.
ParakhTB produces a triage-and-referral call — refer for confirmatory testing, monitor, or no further action. It does not diagnose tuberculosis. Xpert MTB/RIF, culture and chest imaging remain the diagnostic standard.
ParakhTB runs on the SamaClip optical reader validated in an adult cohort (n=175) at the NABL-accredited centre in Barasat, North 24 Parganas. TB-specific performance of the combined urine-and-vitals triage is under validation with our clinical partners and is not yet a published accuracy claim.
