DISCOURAGED

Comment

The Method values "Screen" and "Confirm" reflect a regulatory testing requirement rather than an actual laboratory method. This term has been discouraged in favor of terms specifying the true method (Immunoassay or Mass Spectrometry) or a methodless term where appropriate. Please select the replacement term that matches your actual testing method.

Part Descriptions

LP15016-6   Methaqualone
Methaqualone is a quinazoline derivative with sedative-hypnotic properties. It was used as a treatment of insomnia, as a sedative, and a muscle relaxant. Due to its high potential for abuse, it has been taken off the market in many countries, including the United States. In parts of Africa and India, smoking methaqualone has become a significant public health issue. Methaqualone is similar to barbiturates in that it induces euphoria, sedation and loss of inhibition. This drug functions by binding to GABA receptors in the central nervous system and increasing the amount of inhibitory signals in the brain. Methaqualoneit can be detected during a blood or urine drug test. [PubChem:methaqualone] PMID: 15846700 PMID: 96460 Source: Regenstrief LOINC

LP7238-1   Body fld
The LOINC "Body fld" System represents body fluids other than serum, plasma, blood, urine, and cerebrospinal fluid. When a LOINC term with the System "Body fld" is used, the specific specimen source or body fluid type should be reported elsewhere with the result. Where more specific terms for pleural, peritoneal, synovial fluid, etc. exist, we encourage you to use the more specific terms. In contrast to "Body fld", the System "Asp" in LOINC represents the fluid withdrawn during an aspiration procedure from an abnormal collection of fluid, such as from an abscess or cyst. "Asp" is used for abnormal fluid collections that are aspirated, while "Body fld" is used for named body fluids, such as synovial fluid or peritoneal fluid, that are not inherently pathologic.

Change Reason

The Property has been changed from ACnc to reflect new model for ordinal terms; The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
