Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:The primary weaknesses include the positive samples from a primarily hospitalized cohort, the retrospective nature of samples (including freeze/thaw), and the lack of fingerstick blood samples, for which many of these assays are designed. In a pandemic, reliable information is essential to public health responses and individual healthcare decisions. These results suggest that, with further investigation/data/study/evaluation, LFIAs could potentially be used to meet that need, particularly in low-resource settings or those with limited access to health care. Importantly, it must be noted that detection of IgG does not mean that neutralizing antibodies are present. There is not yet sufficient data in the literature to determine whether detection of IgG may (or may not) correlate with immunity or protection of future exposure to SARS-CoV-2.
