Further Analysis: Further Analysis, as this term is used in the ISL, occurs when a Laboratory
conducts additional analysis on an “A” Sample or a “B” Sample after an analytical result for
that “A” Sample or that “B” Sample has been reported by the Laboratory.
[Comment: There is no limitation on a Laboratory’s authority to conduct repeat or confirmation
analysis, or to analyze a Sample with additional Analytical Methods, or to perform any other type of
additional analysis on an “A” Sample or “B” Sample prior to reporting an analytical result on that Sample.
That is not considered Further Analysis.
If a Laboratory is to conduct additional analysis on an “A” Sample or “B” Sample after an analytical
result for that Sample has been reported (for example: additional Sample analysis to detect EPO, or
GC/C/IRMS analysis, or analysis in connection with the Athlete Biological Passport or additional
analysis on a stored Sample) it may do so after receiving approval from the Testing Authority or Results
Management Authority (if different) or WADA. However, after an Athlete has been charged with a Code
Article 2.1 anti-doping rule violation based on the presence of a Prohibited Substance, Metabolite(s) of
a Prohibited Substance, or Marker(s) of the Use of a Prohibited Substance or Prohibited Method in a
Sample, then Further Analysis on that Sample may only be performed with the consent of the Athlete
or approval from a hearing body (see Code Article 6.5).
Further Analysis may be performed by the same Laboratory that did the original Analytical Testing, or
by a different Laboratory or other WADA-approved laboratory, at the direction of the Testing Authority
or Results Management Authority (if different) or WADA. Any other Anti-Doping Organization that
wishes to conduct Further Analysis on a stored Sample may do so with the permission of the Testing
Authority or Results Management Authority (if different) or WADA and shall be responsible for any
follow-up Results Management. Any Sample storage or Further Analysis initiated by WADA or another
Anti-Doping Organization shall be at WADA’s or that Anti-Doping Organization’s expense.]
Independent Witness: A Person, invited by the Testing Authority, the Laboratory or WADA
to witness the opening and initial aliquoting of an Athlete’s “B” Sample. An Independent
Witness shall not be an employee or have a personal financial relationship with the Athlete or
his/her representative(s), the Laboratory, the Sample Collection Authority, the Testing
Authority / Delegated Third Parties / Results Management Authority or WADA, as applicable.
However, the Independent Witness may be indemnified for his/her service.
Initial Testing Procedure (ITP): An Analytical Testing Procedure whose purpose is to
identify those Samples which may contain a Prohibited Substance, Metabolite(s) of a
Prohibited Substance, or Marker(s) of the Use of a Prohibited Substance or Prohibited Method
or an elevated quantity of a Prohibited Substance, Metabolite(s) of a Prohibited Substance,
or Marker(s) of the Use of a Prohibited Substance or Prohibited Method.
Intermediate Precision (s
w
): Variation in results observed when one or more factors, such
as time, equipment, or operator are varied within a Laboratory. It is also referred to as inter-
batch / inter-run precision.
Laboratory Internal Chain of Custody: Documentation maintained within the Laboratory to
record the chronological traceability of custody (by Person(s) or upon storage) and actions
performed on the Sample and any Aliquot of the Sample taken for Analytical Testing.
[Comment: Laboratory Internal Chain of Custody is generally documented by a written or electronic
record of the date, location, action taken, and the Person performing an action with a Sample or Aliquot.]
Laboratory: A WADA-accredited laboratory applying Test Methods and processes to provide
evidentiary data for the detection and/or identification of Prohibited Substances or Prohibited
Methods on the Prohibited List and, if applicable, quantification of a Threshold Substance in
Samples of urine and other biological matrices in the context of Doping Control activities.
