Intermediate, indeterminate, and uninterpretable
diagnostic test results.
Another problem is that because of poor training, inadequate skills, or incorrect ESU settings, the specimens are uninterpretable
. When this happens, it remains unknown whether the patient has invasive cancer, warts, cervical intraepithelial neoplasia, or nothing.
or missing cases were excluded from the statistical analysis.
The toe-brachial index is a useful test for PAD in patients with noncompressible vessels, which render the ABI uninterpretable
Patients using [beta]-blockers, those with evidence of left bundle-branch block, or those with uninterpretable
5-T segments on the electrocardiogram were also excluded.
The film was returned to the manufacturer for processing and then interpreted by certified evluators as follows: "negative" if normal; "atypical" if there was evidence of an acetowhite lesion outside the transformation zone, or inside the transformation zone but of doubtful significance, or of atypical immature squamous metaplasia; "positive" if there was evidence of minor or major grade lesion or cancer; and "technically defective" if the film was technically uninterpretable
. Cervigram and histologic evaluators were mutually blinded to the results.
For the lung cancer arrays with tandem cores, the following rules were applied: when only 1 core was positive, the case was scored as positive; for cases with 1 uninterpretable
core, the score of the interpretable core was used; when both cores were uninterpretable
(ie, no tumor cells, no viable cells or folded/lost tissue core), the case was scored as uninterpretable
Presence of a novel DNA methylation enzyme in methicillin-resistanl Staphylococcus aureus isolates associated with pig farming leads to uninterpretable
results in standard pulsed-field gel electrophorcsis analysis.
DNA-based diagnosis of AIP was particularly useful in the proband as RBC HMBS activity is uninterpretable
in the presence of hemolysis.
Any specimen lacking intrinsic elements (normal breast epithelium) that is negative on ER and/or PgR assay should be repeated using another tumor block or another tumor specimen and reported as uninterpretable
rather than as negative.
In our study, only 6 blood samples were collected for culture, and they were uninterpretable
because of contamination.
By using a parameter such as PDW that, although routinely available, is generally considered an uninterpretable
result, we were able to achieve a fairly interesting resolution between reactive and autonomous thrombocytosis.
