Study summary

A prospective cross-sectional study in which surgically non-invasive sample-taking is done only for the purpose of the study. Capillary (fingerstick) whole blood and EDTA venipuncture whole blood are collected by a healthcare professional. The collected samples of capillary and EDTA whole blood are tested on iStatis and EDTA whole blood sample will be processed to obtain serum and plasma samples to be tested on the iStatis. An aliquot of the collected serum sample will be shipped to the central laboratory for confirmatory testing. The results from iStatis HBsAg Test results will not be used for patient management decisions.

Read the detailed description

From each enrolled patient, a total of 2 different blood samples (capillary and venous whole blood) will be collected, processed, and categorized under the following categories:

  • Sample 1: 50μL of Capillary (fingerstick) (see section 8.6.2) Sample 2: 16ml of Venous whole blood (further extraction of serum, and plasma samples) (see section 8.6.2) Sample 1 consisting of capillary (fingerstick) and Sample 2 venous whole blood sample will be tested on iStatis HBsAg Test on site according to the 'Test Procedure' described in the Instructions for Use (IFU) supplied with the reagents. Sample 2 containing of 1 EDTA and SST venous whole blood samples will be separately processed to obtain plasma and serum samples, respectively, and will be tested onsite on the iStatis. An aliquot of the serum sample stored and frozen at -20ᵒC at the testing site will be transferred to the central laboratory to establish further reference testing. Upon arrival of the sample, it will undergo an initial test using DiaSorin Liaison XL Murex HBsAg Quant Assay, REF. [310250] following the IFU of this reference assay. If the first run of the assay yields a "non-reactive/Negative" result, it will be reported as such. However, if the sample is "Reactive/Positive" in the first run of the assay testing, it will be retested on the same assay in duplicate, following the manufacturer's instructions. A final "Reactive/Positive" result means that at least one of the duplicate repeat tests was reactive, if neither of the duplicate repeat tests yields a reactive results, the final report in the DiaSorin Liaison XL Murex HBsAg Quant Assay requires three tests to confirm. Samples with a reportable "Reactive/Positive" result in the DiaSorin Liaison XL Murex HBsAg Quant Assay will undergo further testing using DiaSorin Murex HBsAg Confirmatory assay, REF. [9F80-01]. A "Reactive/Positive" result in this test will confirm the presence of the relevant marker.

Inclusion criteria

  • Patients/subjects (males, females, and pregnant women) getting tested for for one or more of the following reasons:

    • at risk for HBV
    • having signs and symptoms indicative of HBV
    • pregnant and have HBV.
    • Re-infected with HBV (previously positive)
  • Patients/subjects of 18 years or older and, who are able to give/sign the .

Exclusion criteria

Exclusion Criteria:

  • Patient younger than 18 years old
  • Patients unable to provide written .
  • Patients currently undergoing treatment
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Apr 2024 to primary completion in Jul 2024, 2 months.

Of 68 interventional studies with no phase under Hepatitis B, half reached primary completion within 29 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 47. This study's 2 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 21, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
