Molecular biology and genetics | Generic abbreviated | NPU53991 DNA fragment(P)—DNA fragment(Chromosome 13); arb.fr.(proc.) = ? |
Full result | NPU53991 DNA fragment(Plasma)—DNA fragment(Chromosome 13); arbitrary fraction(procedure) = Low | |
Abbreviated result | NPU53991 DNA fragment(P)—DNA fragment(Chromosome 13); arb.fr.(proc.) = Low | |
Written expression | The arbitrary fraction of DNA fragment(Chromosome 13) of all DNA fragment in Mrs. Smith’s plasma is low. | |
Notes |
“Low” is a value according to a value set defined by the laboratory. Fraction of DNA fragment(Chromosome 13) is the quotient of DNA fragment(Chromosome 13) divided by all DNA fragments in Mrs. Smith’s plasma. |
