Glossary Term
Any of various amplification and detection strategies applied to detection of virus contamination in donor blood. Specifically designed to detect recently infected individuals during the latency period before seroconversion.
Pcr Terms
Glossary Term
The sample-preparation stage that lyses cells or virions and purifies DNA/RNA before amplification. Extraction quality (yield, purity, inhibitors removed) often limits assay performance more than the PCR itself, and it defines required instruments and hands-on time in a workflow.
Extraction Methodology
Glossary Term
Laboratory procedure in which single stranded nucleic acids are allowed to interact so that complexes, or hybrids, are formed by molecules with sufficiently similar, complementary sequences. By this means the degree of sequence identity can be assessed and specific sequences detected. (From Biology-online)
Pcr Terms
Glossary Term
A subunit of DNA or RNA consisting of a nitrogenous base (adenine, guanine, thymine, or cytosine in DNA; adenine, guanine, uracil, or cytosine in RNA), a phosphate molecule, and a sugar molecule (deoxyribose in DNA and ribose in RNA).
Pcr Terms
Glossary Term
Nucleotide Excision Repair (NER) mends DNA regions that contain chemical adducts, such as UV-induced thymine dimers or carcinogenic adducts, which distort the DNA helix and interfere with replication and transcription. NER is targeted to actively transcribed regions of the genome. During NER in eukaryotes, shape irregularities are detected by protein complexes that slide along the DNA molecule and induce cuts on each side of a lesion several nucleotides away. Removal of the damaged 25-30 nucleotide fragment is followed by repair synthesis and ligation.
Pcr Terms
Glossary Term
A statistical method to test if observations are significant or due to chance. It proposes that no statistical significance exists in a set of given observations and attempts to show that no variation exists between variables or that a single variable is no different than its mean. It is presumed to be true until statistical evidence nullifies it for an alternative hypothesis.
Performance Metrics
Glossary Term
The ratio of the odds of an event occurring in one group to the odds of it occurring in another group, or to a sample-based estimate of that ratio.
Performance Metrics
Glossary Term
Short DNA oligonucleotide chains used to prime DNA (and in some cases RNA) synthesis.

Opioid testing looks for opioids in a sample of your urine (pee), blood, saliva (spit), hair, or sweat.
