For quality control, all positive specimens and a random sample of 5% of negative specimens was retested in a different laboratory using the same testing algorithm.
In the vibrant hothouse that is Chris Garofalo's Chicago studio, nearly every surface holds carefully composed displays — natural specimens, souvenir postcards, family photos and random objects, like a petrified frog or lurid blue ceramic eggplants.
One to two weeks later, women who tested positive for any of the six screening tests performed (VIA, HPV E6, and HC2 and careHPV™ on clinician-collected and self-collected specimens) and approximately a 10%% random sample of women who tested negative for all screening tests (screen-negative women) were called back to undergo a second VIA and a rigorous colposcopic evaluation.

The robustness and consistency of the packing method were proved by generating different digital specimens with random selection and placement of aggregates having the same gradation.
Blood and random spot urine specimens were obtained for laboratory analyses, and medical records were reviewed to obtain information on their metabolic control and the presence of comorbidities and complications.
Briefly, the orientator method is an approach for generating isotropic, uniform, and random sections of biological specimens that allows for the quantitative study of three-dimensional anisotropic structures from the two-dimensional sections.
A previous study examined the incidence of horizontal cleavage lesions of the knee menisci in 100 random necropsy specimens and found that the coincidence of horizontal cleavage lesions and OA was frequent [ 6].
The most common findings that are highly suggestive of DC and can also be expected in biopsy specimens include random distribution of ductal structures, irregular ductal contours, nuclear enlargement (>3 times the size of a lymphocyte), and pleomorphism, distinct nucleoli, and mitosis.
The specimens underwent random vertical sectioning on a Leiden microtome (Leiden, Holland), and were counterstained with 2% light green (Overgaard et al. 2000).
