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.

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.
