Some of these questions were used in the PISA 2000, 2003 and 2006 surveys and others were used in developing and trying out the assessment. It is normally a good practice to perform pilot studies to validate new specimen collection methods and protocols (4). For the first time a method was standardised for semen collection from the White backed vulture. Clinical relevance The combined results of the saliva and self-swab test achieve a sensitivity equivalent to that of a health care worker administered swab. Uric acid is the ultimate catabolite of purine metabolism in humans and higher primates. We designed a storage buffer for preventing DNA from degradation on saliva samples. Saliva collection was performed with a commercially available Salivette (Sarstedt) following the manufacturer’s instructions. Two common, well-documented methods of saliva collection are: (1) the passive drool technique, and (2) the absorbent device technique. Specimen Collection • Suspect or confirmed TB patients should be in a negative pressure room • Specimen collection is an aerosol generating procedure, anyone in the room during specimen collection must wear a particulate respirator type N-95 and be part of the respirator protection plan • All mycobacteria specimens are collected Saliva can be expressed from the swab after thawing by centrifugation at 1500 g for 15 minutes, or by squeezing the swab in the chamber of a 5 cc syringe and expressing the liquid into a cryovial. Saliva is typically found on a substrate, most often a cigarette, sealed envelope, stamp, or eating/drinking utensil. Common methods include the draining method, the spitting method, the suction method, and the swab method [ 27 ]. based methods for bird species identification have also been developed. The efficiency of this buffer to prevent DNA degradation was tested on 10 samples at room temperature for up to 24months. All of these methods enable detection of specific molecules like cortisol, C-reactive protein (CRP), or secretory IgA.
