Tests
A two-staged test with purified coagulation factors in the first stage, and a FXa-specific chromogenic substrate in the second stage. In the first stage, diluted sample plasma, which has been treated with Al(OH)3 to remove prothrombin, is mixed with a combined reagent (human serum, factor V, phospholipids and calcium). In the second stage, a subsample from the first stage is mixed with normal plasma, providing prothrombin and fibrinogen, and the clotting time is measured to deduce the amount of FVIII present.

This gene is involved in RNA binding and pre-mRNA splicing.
Glossary Term
Ubiquitin is a family of widely distributed proteins found in all eukaryotes that contain a highly conserved sequence of 76 amino acids identical in organisms from humans to insects. It participates in diverse cellular functions by conjugation to other proteins through its carboxy terminus. Ubiquitination is associated with many highly regulated biological events including protein degradation, chromatin remodelling, heat shock, cell cycle progression, differentiation, antigen presentation, retrovirus assembly, apoptosis, signal transduction, transcriptional activation, biological clocks, receptor down regulation, and endocytosis. Protein ubiquitination regulates the half-lives of many proteins by targeting them for degradation. Newly discovered families of ubiquitination and deubiquitination enzymes participate in these processes. Ubiquitination enzymes may provide new therapeutic targets and ways of intervention in many human diseases.
Pcr Terms
Glossary Term
Short random nucleotide sequences that are ligated to each primer molecule during amplification of a nucleotide sample during library preparation to act as a unique tag. Their use helps to identify PCR duplicates in sequencing data.
Pcr Terms
Glossary Term
The product of so-called RNA genes; a functional RNA represents the final product of a gene rather than a transient molecule that will be translated into protein.

Tests
A uric acid test measures the amount of uric acid in a sample of your blood or urine (pee). Uric acid is a normal waste product that your body makes when it breaks down chemicals called purines. These chemicals come from your cells when they die and can be found in certain foods and beverages.

Tests
A urobilinogen in urine test measures the amount of urobilinogen in your urine (pee). Urobilinogen comes from bilirubin. Your body makes bilirubin during the normal process of breaking down old red blood cells. Your liver uses the bilirubin to make bile, a fluid that helps you digest food in your intestines. Some bile flows through your bile ducts (small tubes) from your liver directly into your intestines. The rest is stored in your gallbladder for when you need it.

Glossary Term
The act of validating; finding or testing the truth of something.
Regulatory Definitions
Glossary Term
A measure of the variability in a sample or population. It is calculated as the mean squared deviation (MSD) of the individual values from their common mean. In calculating the MSD, the divisor n is commonly used for a population variance and the divisor n-1 for a sample variance.
Performance Metrics
Glossary Term
The relative rate of occurrence of a specific variant allele compared to the total number of alleles at that locus in the sample. This measurement may be reported as a ratio or percentage.
Pcr Terms
Glossary Term
An alteration or difference from a norm or standard.
