Ebola antigen testing - five-strain coverage

Bundibugyo ebolavirus is not an edge case. GoldN covers it.

GoldN™ Easy to Use Ebola Rapid Antigen Test was developed to detect five Ebolavirus strains from a 15 µL fingerstick blood sample in 15 minutes, with no observed Marburg VP40 cross-reactivity in specificity testing.

Coverage led by BEBOV
Detects five Ebolavirus strains without observed Marburg VP40 cross-reactivity.
0.1 ng/mL LoD
Lower analytical LoD than listed comparators (53 ng/mL OraQuick, 250 ng/mL DPP)

Strain coverage

Five Ebolavirus strains. Bundibugyo highlighted.

GoldN™ Easy to Use Ebola Rapid Antigen Test detects ZEBOV, SEBOV, BEBOV, TAFV, and RESTV. Specificity testing showed no observed Marburg VP40 cross-reactivity.

Primary differentiator

Bundibugyo ebolavirus

BEBOV is included in the coverage set, giving GoldN™ Easy to Use Ebola Rapid Antigen Test broader listed Ebolavirus inclusivity than comparator entries with Zaire-only coverage.

ZEBOV
Zaire ebolavirus

Included in comparator and assay coverage data.

SEBOV
Sudan ebolavirus

Included for multi-species Ebolavirus response.

TAFV
Taï Forest ebolavirus

Included in the five-strain coverage set.

RESTV
Reston ebolavirus

Included in the five-strain coverage set.

Test workflow

Built around a 15 µL fingerstick blood sample.

GoldN™ Easy to Use Ebola Rapid Antigen Test keeps the first-use workflow simple while preparing for GoldN Reader-enabled track, trace, and semi-quantitative result capture.

01

Collect fingerstick blood

Use a 15 µL fingerstick blood sample for the Ebola antigen test workflow.

02

Apply sample and buffer

Add the blood sample and assay buffer to the cassette according to instructions.

03

Wait 15 minutes

The lateral-flow strip develops a control line and test line pattern.

04

Read the result

The test can be read visually. The next frontier is the GoldN Reader for track, trace, and semi-quantitative fluorescence readout.

Differentiation

Five-strain coverage. Low sample volume. 15-minute result.

GoldN™ Easy to Use Ebola Rapid Antigen Test combines five-strain Ebola coverage, a 15 µL fingerstick blood sample, 15-minute results, and a GoldN Reader path for semi-quantitative fluorescence readout.

01

Bundibugyo included

BEBOV coverage is built into the five-strain Ebola antigen claim set.

02

No observed Marburg VP40 cross-reactivity

Specificity testing showed Ebola VP40 reactivity without observed Marburg VP40 reactivity.

03

Lower analytical detection limit

0.1 ng/mL or 0.0015 ng/test analytical sensitivity in feasibility data.

04

Reader-ready next step

GoldN Reader adds track, trace, and semi-quantitative result capture for clinical validation programs.

Comparator snapshot

Five-strain coverage and lower analytical LoD in the comparator set.

Lower analytical detection limit indicates higher analytical sensitivity. Comparator values support procurement review and clinical-validation discussions.

Next frontier

GoldN Reader: track, trace, and semi-quantitative readout.

GoldN™ Easy to Use Ebola Rapid Antigen Test can operate as a visual rapid antigen test. The GoldN Reader adds fluorescent signal reading, semi-quantitative result capture, and traceable testing records for clinical validation and outbreak programs.

  • Reads fluorescence signal from the lateral-flow cassette.
  • Tracks test events and supports traceable result records.
  • Supports semi-quantitative output for validation datasets.
