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

Chromosome Analysis, Chorionic Villus : 2002291

Time Sensitive

Patient History for Prenatal Cytogenetics

Mnemonic: CHR CVS

Methodology:	Giemsa Band
Performed:	Sun-Sat
Reported:	7-14 days
Specimen Required:	Collect: Thaw media prior to collection. Chorionic villus in a sterile, screw-top container filled with tissue culture transport medium (ARUP Supply #32788). Available online through eSupply using ARUP Connect™ or contact ARUP Client Services at (800) 522-2787. If cytogenetics tissue media is not available, collect in plain RPMI, Hanks solution, saline, or ringers. Specimen Preparation: DO NOT FREEZE. Do not place in formalin. Transport chorionic villus (CVS) specimen in a sterile, screw-top container filled with tissue culture transport medium. If specimen size is too large for a normal collection tube, a larger sterile container can be used such as a sterile urine cup and can be flooded with several tubes of cytogenetic tissue media. Storage/Transport Temperature: Room temperature Remarks: This test must be ordered using Cytogenetic test request form #43097 or through your ARUP interface. Submit the Patient History for Prenatal Cytogenetics form with the electronic packing list (available at http://www.aruplab.com/genetics/forms.php). Unacceptable Conditions: Frozen specimens. Specimens preserved in formalin. Stability (collection to initiation of testing): Ambient: 24 hours; Refrigerated: Unacceptable; Frozen: Unacceptable

Reference Interval: By report
Interpretive Data:	Counseling and informed consent are recommended for genetic testing. Consent forms are available online at www.aruplab.com.
Note:	These studies involve culturing of living cells; therefore, turnaround times given represent average times which are subject to multiple variables. After specimen receipt, results are generally available in an average of 12 days. A processing fee to cover sex confirmation and rule out maternal contamination by FISH is added to all Chromosome Analysis, Chorionic Villus Sampling (CVS) tests. An additional processing fee will be charged if this procedure is canceled at the client's request, after the test has been set up, or if the specimen integrity is inadequate to allow culture growth.
CPT Code(s):	88269 Chromosome analysis in situ; 88235 Tissue culture; 88280 Additional karyotype; 88291 Interpretation and report - Additional CPT code modifiers may be required for procedures performed to test for oncologic or inherited disorders.
