This is required as not all positive tests represent true "disease" (e.g., C. difficile in children <1 year rarely causes disease) [ 39].
We can therefore not establish whether the positive test result represents treatment failure, lack of partner treatment or a new infection with a new sexual partner.
This analysis together with the visual inspection of the plots clearly suggest that the evaluation of any biomarker of PAE should be conducted under different perspectives, especially if a false positive test might represent an enormous social and legal burden, such as those faced by pregnant women who are mislabeled as alcohol drinkers.
Positive test results represent "albuminuria" in these guidelines, corresponding to protein excretion of >300 mg/24 h, >200 μg/min, or >300 mg/g creatinine (Table 8).
Interestingly, 65% of the tested HD and GATA TFs (9/14 and 4/6, respectively) were positive in the competition test, representing a strong tendency compared to the other tested TF classes.
However, many of these positive tests either represent sub-clinical infections, or identify recent, but not acute infections.
In a location where almost one in every five pregnant women is HIV-positive, every woman who refuses HIV testing represents an important missed chance to prevent mother-to-child transmission and promote maternal and child health.
Combined this indicates that persistent positive QFT-TB tests represent persistence of pre-treatment IFN-γ responses.
These outcomes include whether the initial positive test results or symptoms represented a false positive or whether they served as the first sign of a true recurrence, as well as subsequent resource use for both true and false positives.
Based on data from the UK, 2.3% of all women with a false positive test had a lumpectomy, representing 76 out of 100,000 women screened in one screening round [ 22].
