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

Alpha Fetoprotein (Amniotic Fluid) with Reflex to Acetylcholinesterase and Fetal Hemoglobin : 0080427

Patient History for Prenatal Cytogenetics

Mnemonic: AFP AF

Methodology:	Chemiluminescent Immunoassay/Electrophoresis
Performed:	Sun-Sat
Reported:	3-4 days If reflexed, Acetylcholinesterase results are reported 7-10 days after completion of the AFP.
Specimen Required:	Patient Prep: Amniocentesis. Collect: Amniotic fluid. Specimen Preparation: Transport 2.5 mL amniotic fluid. Storage/Transport Temperature: Refrigerated. Remarks: Include gestational age at time of collection on the test request form. The following information is required and must accompany the specimen in order for testing to be interpreted: Patient's date of birth, due date, weeks of gestation, and physician's name and phone number. Unacceptable Conditions: Specimens contaminated with fetal blood. Stability (collection to initiation of testing): Ambient: 72 hours; Refrigerated: 1 week; Frozen: 1 year

Reference Interval:

Test Number	Components	Reference Interval
2002387	Acetylcholinesterase and Fetal Hemoglobin	By report
	AFP, Amniotic Fluid	By report Ranges are based upon the weeks of gestation.

Note:

Information must include weeks of gestation. If the AFP (amniotic fluid) is elevated, then acetylcholinesterase will be added. Additional charges apply. Acetylcholinesterase testing requires an additional 7-10 days to be reported.

CPT Code(s):

82106 AFP; if reflexed, add 82013 Acetylcholinesterase and 83033 Fetal Hemoglobin
