Typical processing steps performed when analyzing laboratory results

Step	Description
1. Retrieve all relevant results	Given the relevant high-level attribute identifiers in the system (eg, CYP2C19 Results), retrieve all descendant attribute identifiers, and then pull all result values of those attribute types.
2. Normalize SNP genotypes	Ensure 2 SNP genotypes are present with no additional characters separating them (eg, A/A -> AA or T -> TT).
3. Convert SNP genotypes to pharmacogenetic star alleles	Using a lookup table, translate the SNP genotype(s) to the appropriate star alleles as necessary.
4. Normalize star alleles	Ensure 2 star alleles are present with no additional characters separating them (eg, *1/*1 -> *1*1).
5. Convert genotype to observation	Using a lookup table, translate the star variant or alleles into the appropriate computed observation representation.
6. Generate report from template	Given the computed observation and original genotype results, generate an interpretive report.

Depending on the type of data present, certain steps did not apply.

SNP: single nucleotide polymorphism.
