Two tests. One dual-flow platform.

BQL-TB targets the world's leading infectious killer.
BQL-Stress brings lab-grade cortisol quantification to wellness, occupational,
and mental-health settings. Both run on the same architecture.

product 01 - Tuberculosis Rapid Diagnostic

BQL-TB.
Catching latent tuberculosis in 15 minutes, anywhere.

A high-sensitivity, dual-flow colorimetric rapid diagnostic test targeting urinary TB-LAM, the only validated non-sputum TB biomarker. A single 120 µL urine loading produces a naked-eye-readable result in 15 minutes at a per-test cost below US$1. No laboratory, no dedicated reader, no additional user steps.

Sample

Urine, 120 µL, single load

Time

15 minutes

Readout

Naked-eye + optional AI smartphone app

Current LoD

980 pg/mL (target <100 pg/mL)

WHO TPP target

≥65% sensitivity / ≥98% specificity

Cost

< US$1 per test

Storage

Targeting 10–37°C, ≥12-month shelf life

Status

Lab-validated · FDA pre-submission planning

STEP 01

Load urine sample

Patient or care provider drops 120 µL of unprocessed urine onto the cartridge sample port. No preparation, no centrifugation.

STEP 02

Wait 15 minutes

Upper path reconstitutes HRP-anti-LAM antibodies; lower path delivers TMB substrate via the PVDF delay pad. Enzyme amplification produces a blue colorimetric signal.

STEP 03

Read result

Visible test/control lines readable by the naked eye. Optional smartphone app provides quantitative readout, ratiometric T/C normalization, and cloud sync.

product 02 - Cortisol Point-of-Care

BQL-Stress.
Quantifying cortisol at the point of care.

A digital healthcare system and point-of-care device for measuring cortisol (stress hormone) levels, built on a polymer Lab-on-a-Chip platform with a published reference in Biomedical Microdevices. Designed for integration with wellness, occupational health, and mental-health screening workflows.

Sample

Usecase 01

Digital wellness

Integration with consumer wellness platforms tracking stress over time, with smartphone-paired readouts and longitudinal cloud sync.

Usecase 02

Occupational health

Workplace stress monitoring, particularly for high-cortisol-exposure roles in healthcare, emergency services, and aviation.

Usecase 03

Mental-health screening

Adjunctive biomarker for chronic stress, anxiety, and burnout screening in primary care and telehealth.
