A number of different immunoassay techniques (FDA).

(*) Urine specimens are defined in PD #35 as "dilute" if the Urine specimens are defined in PD #35 as "dilute" if the creatininecreatinine concentration is < 20 mg/dL and the concentration is < 20 mg/dL and the specific gravity specific gravity is < 1.003. An analysis of that review resulted in selecting urine is < 1.003. An analysis of that review resulted in selecting urine creatinine < 5 mg/dL and urine specific gravity <1.001 or creatinine < 5 mg/dL and urine specific gravity <1.001 or >1.020 as the criteria to define a "substituted" specimen.>1.020 as the criteria to define a "substituted" specimen.

“Sample integrity failed” Samples with creatinine results less than or equal to 0.5

mmol/l (56 mg/l) or specific gravity results out of range are unsuitable for testing.

Measurement of pH: Results within the range 4-9 are deemed to be within a normal range. Results less than 3 or greater than 11 should be considered to be adulterated. Samples falling outside this range should be reported as eg “sample integrity failed”.

Nitrite test: If the nitrite concentration is determined: A nitrite level equal to or above 500 μg/ml is conclusive proof of an adulterated sample. The result should be reported as eg “sample integrity failed”.

Testing for other adulterants: If other tests indicate that the sample has been adulterated, or is otherwise unsuitable for analysis then it should be reported as eg “sample integrity failed”

This remark is also reported when the sample does not fall under the criteria of pH, creatinine or nitrite above, yet is still not suitable for testing. This can be due to an unidentified interferant or poor sample quality such as turbidity.

European Laboratory Guidelines for Legally

DefensibleWorkplace Drug Testing

(EWDTS)Objectives The guidelines are designed to: 1 Provide a minimum set of criteria for the providers of workplace

drug testing services within Europe. 2 Ensure that the processes undertaken are capable of legal

scrutiny. 3 Provide safeguards to protect the specimen donors. 4 Define for laboratories common quality assurance and quality

control criteria that are capable of being accredited by an external body.

Scope These guidelines consider the three key stages of the workplace drug testing process. 1 Obtaining the specimen from the donor (specimen collection). 2 Analysis of the sample for the presence of drugs (laboratory

analysis). 3 Review and interpretation of the analytical results

When a positive result:When a positive result: When a positive result:When a positive result:

Long-term frozen storage (-15°C or less) for any necessary retest, storage for a minimum of 1 year.

Quality system (ISO 17025 must apply) which encompasses all aspects of the testing process including but not limited to: Sample receipt. Chain of custody. Security and reporting of results. Screen and confirmation testing. Certification of calibrators and controls. Validation of analytical procedures.

Interpretation resultsInterpretation results An analytical positive result may be due to

medication (prescribed or over-the-counter) or to dietary causes. An essential part of the drug testing process is the final review of positive analytical results.

The interpretation is best carried out by a qualified medical practitioner (Medical Review Officer) who can consult with the laboratory toxicologist, the donor, and the donor's medical practitioner.

A toxicologist must be available to advise the customer and/or Medical Review Officer regarding queries with results. The toxicologist cannot issue a negative report for a positive analytical result even if the test result is likely to be due to the use of declared medication.

Some examples of prescription and over-the-counter drugs: Analgesics Aspirin w/codeine, Codeine, Darvocet, Darvon, Demerol, Dilaudid, Empirim Compound w/codeine, Levo-Dromoran, Methadone, Percocer, Percodan, Soma Compound s/codeine, Talacet, Talwin, Tylenol w/codeine, and Vicodin.

Medical Review

(a) The Medical Review Officer (MRO) is a medical physician with

responsibility for interpreting laboratory results.

(b) A medical physician will have greater access to medical records than a toxicologist and may therefore be in a better position to provide interpretation of positive analytical results.

(c) The MRO must have specialist knowledge of and training in · Specimen collection procedures.

· Analytical procedures.

· Chain of Custody.

· Alternative explanations for positive analytical results.

(d) The MRO can issue a negative report for a positive analytical result if the test result is likely to be due to the use of

declared medication, or a valid alternative explanation has been found.

(e) The service provider may provide access to an independent medical review service.
