Search Tips

Wildcards Symbol (*)

The wildcard symbol (*) can be used in place of letters or characters in query words to search for different permutations of a word.

*	Can be in any position in the term and matches any number of characters.
Examples:	hemo*	matches hemolytic, hemophilia and hemophilia
	*NA	matches DNA and RNA
	*tet**	matches text and test
	BCL*	matches bcl-1/JH and bcl-2/JH
	virus*	matches virus or viruses
	*glucan*	matches beta-1,3-d-Glucan

Boolean Parameters

Search terms can be a single word or several words. The search engine automatically inserts and between words if nothing else is specified, so the Boolean term and can be omitted in search terms. For example, searching for tissue assay is the same as searching for tissue AND assay.

Quotes can be used to search for phrases. For example:

"tissue assay "

Words must be present in the specified order with no intervening words

The following boolean connectors can be used: AND, OR, NOT Examples:

tissue AND assay	Both words must be present
tissue OR assay	Either word can be present
assay NOT tissue	Only assay can be present, tissue cannot appear on the page

HNPCC/Lynch Syndrome Deletion/Duplication : 2001728

Patient History for HNPCC/Lynch Syndrome Testing

Mnemonic: HNPCC DD

Methodology:	Polymerase Chain Reaction/Multiplex Ligation-dependent Probe Amplification
Performed:	Varies
Reported:	Within 14 days
Specimen Required:	Collect: Lavender (EDTA), pink (K₂EDTA), or yellow (ACD Solution A or B). Specimen Preparation: Transport 3 mL whole blood. (Min: 1 mL) Storage/Transport Temperature: Refrigerated. Stability (collection to initiation of testing): Ambient: 72 hours; Refrigerated: 1 week; Frozen: Unacceptable

Interpretive Data:	Refer to report. Counseling and informed consent are recommended for genetic testing. Consent forms are available online at www.aruplab.com. Refer to Statement C under Testing Information at http://www.aruplab.com.
Note:	Available for MLH1, MSH2, MSH6 or PMS2 genes. For PMS2 testing, suspected deletions or duplications in exons 12-15 require sequencing to exclude pseudogene copy number variants. Additional charges apply.
CPT Code(s):	83891 Isolation; 83896 x10 Nucleic Acid probes; 83898 x10 Amplification; 83914 x10 Extension; 83909 Capillary electrophoresis; 83912 Interpretation and report. If sequencing is performed for PMS2, add 83898 x10 Amplification; 83904 x8 Sequencing; 83909 Capillary electrophoresis. - Additional CPT code modifiers may be required for procedures performed to test for oncologic or inherited disorders.
