Objective: To compare DNA yield from neonatal umbilical cord blood and buccalswab specimens.
2
Materials & methods: A saliva and four buccalswab samples were taken from 104 patients.
3
Winston's DNA was recently obtained through a buccalswab he provided to authorities investigating the case.
4
Methods and material: The buccalswab specimens were collected and β-globin gene DNA sequencing was done.
5
We examined Mycobacterium tuberculosis DNA detection from buccalswab samples collected from children in Lima, Peru.
1
Darby did an oralswab on the insides of the woman's cheeks.
2
Repeated non-invasive oralswab sampling in one holding indicated positive animals months after a first negative result.
3
The most common error that affected test performance was incorrect specimen collection ( oralswab or finger prick).
4
Canadian-born Michael Ibsen, a direct descendant of Richard III's eldest sister, Anne of York, uses an oralswab to give a DNA sample to researchers.
5
Semiquantitative microbiological cultures of oralswabs were also obtained on same days.

1
The aim of this study was to determine optimal timing and technique for buccalsmear collection in breast-fed infants in order to avoid diagnostic errors.
2
Buccalsmear analysis is a noninvasive, fast, and relatively inexpensive diagnostic method.
3
Buccalsmears should not be obtained in nursing neonates until at least 60 min after breast feeding.
4
Previously we have shown that maternal cells can contaminate buccalsmears taken from breast-fed infants, resulting in difficulty with test interpretation.
