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

Oxygen Dissociation (P50) by Hemoximetry : 2002984

Time Sensitive

Patient History for Hemoglobinopathy/Thalassemia Testing

Mnemonic: HEMOX

Methodology:	Spectrophotometry/Clark Electrode
Performed:	Mon-Fri
Reported:	1-3 days
Specimen Required:	Patient Prep: A control specimen needs to be sent with the patient specimen. The control specimen needs to be drawn from a healthy, non-smoking, individual who is not biologically related to the patient. Collect: Lavender (EDTA) (patient) AND lavender (EDTA) (control). Collect control specimen within 30 minutes of patient specimen and keep specimens together at all times. Specimen Preparation: Refrigerate immediately after collection. Transport 5 mL whole blood (patient) AND 5 mL whole blood (control). (Min: 1 mL (patient) AND 1 mL (control)) Label the control tube as "Control for [patient name]". Storage/Transport Temperature: Refrigerated. Send Sunday-Thursday only. Specimens should be received within 24 hours of collection. Ship patient and control specimens together. Unacceptable Conditions: Frozen or room temperature specimens. Specimens submitted without a control. Stability (collection to initiation of testing): Ambient: Unacceptable; Refrigerate: 72 hours; Frozen: Unacceptable

Reference Interval: Effective August 15, 2011 22-28 mmHg
Note:	Test is not orderable for New York clients because of short stability. New York clients should submit specimens directly to a New York approved laboratory. For all other clients, if multiple patients are being drawn at one time, it is acceptable to submit one control for all patients. Label control specimen as: "Control for (list all patient names)."
CPT Code(s):	82820
