1. Introduction

Testing and Calibration laboratories are required to comply with the

requirements of ISO/IEC 17025:2005 ‘General Requirements for the

Competence of Testing and Calibration Laboratories’ and Medical Testing

laboratories have to comply with the requirements of ISO 15189:2007

‘Medical laboratories – Particular requirements for quality and

competence’.

One of the pre-requisite for seeking NABL Accreditation is that applicant

laboratory shall submit its Quality Manual, describing its policies, the

structure of management system documentation and compliance to

ISO/IEC 17025 or ISO 15189, as applicable & relevant NABL Specific

Criteria. NABL therefore, decided to publish this document as a help to

applicant laboratories.

In preparing the Quality Manual, it should not be restricted to the contents

of this guide. However, all elements of ISO/IEC 17025 or ISO 15189 as

applicable must be addressed in the intended Quality Manual. As an

illustration this document provides guidance to Testing and Calibration

laboratories for addressing the requirements of ISO/IEC 17025 in their

Quality Manual. Similarly, the requirements of ISO 15189 can be

addressed by Medical Testing laboratories in their Quality Manual.

The amount of details to be provided in the manual will vary depending

upon the size, field of activities, and nature of testing / calibration

performed by the laboratory. The Quality Manual shall include or make

reference to other documents such operational procedures, work

instructions, forms etc.

For preparing the Quality Manual, the laboratory may also get its technical

personnel trained in NABL’s training programme on management system

for laboratory personnel. A calendar of such training courses is regularly

published in the NABL News.




2. Process of preparing a Quality Manual

The management should nominate individuals from one or more functional

area/ section of the laboratory and a Quality Manager, having a

background of Management Systems. This group should get fully

acquainted with all NABL documents and understand the assessment

procedure & methodology of making an application. Relevant requirements

for NABL accreditation should be discussed amongst concerned staff of

the laboratory. The team should collectively make the effort to prepare the

Quality Manual with the guidance of the Quality Manager.

Laboratory needs to ascertain the status of its existing management

system and its competence. For that all existing policies, objectives,

procedures, work instruction whether documented or otherwise are

required to be listed and compared with the requirements of

ISO/IEC 17025 or ISO 15189 as applicable, relevant NABL Specific criteria

and other requirements.

The laboratory should examine that the existing management system is

appropriate or it needs modification or it needs to be built from scratch.

The laboratory will be able to decide. However, it is advisable that the

laboratory writes the manual afresh, as the elements of ISO/ IEC 17025 or

ISO 15189 are quite different from other Quality Management System

standards, even though the system elements are similar.

It must be remembered that Quality Manual is a policy document, which

has to be supplemented by a set of other documents like procedure

manuals, work instructions, forms, reports etc. to align the management

system in accordance with ISO/IEC 17025 or ISO 15189, as applicable

and relevant NABL specific criteria. Therefore, the management system of

the laboratory needs to be structured.




The management system of the laboratory can be structured in many

ways. A typical structure of management system document hierarchy,

generally followed, is given below:

QualityManual

(Level A)

Management systemProcedures

(Level B)

Other quality documents(Work instructions, forms, reports, etc.)

(Level C)

The order of development of a hierarchy for an individual laboratory

usually starts with the development of the laboratory’s Quality Policy &

objectives followed by the implementation plan of the various elements of

ISO/IEC 17025 or ISO 15189 as applicable in brief. This is the apex

document or Level A document termed as the ‘Quality Manual’.

The Quality Manual has to be supplemented by a set of management

system procedures, Level B documents, which describe the detailed

procedures of the activities of individual function units needed to

implement the management system. All procedures are cross referred in

the Quality Manual.

Management system procedures may further be supplemented with

detailed work instructions, forms, reports etc. termed as Level C

documents. In some hierarchy systems, forms and reports may be grouped

as Level D documents.




The quantity of documented procedures, work instructions, forms, reports

etc. and the nature of their format and presentation are to be determined

by the individual functional units. However, it is preferred that each of

these set of documents are arranged in the same structure and format so

that the users become familiar with the consistent approach applied to

each requirement and to improve the likelihood of systematic compliance

with ISO/IEC 17025 or ISO 15189 as applicable.




3. Structure and Format of Quality Manual

There is no required structure or format for a Quality Manual. However,

any Quality Manual should convey accurately, completely and concisely

the Quality Policy, objectives, address or reference to the next level of

documentation and management responsibilities of the laboratory. One of

the methods of assuring that the subject matter is adequately addressed

and located would be to align the sections of the Quality Manual to the

elements of the ISO/IEC 17025 or ISO 15189 as applicable. Other

approaches, such as structuring the manual to reflect the nature of the

laboratory or nature of work carried out by the laboratory are equally

acceptable.

This guide is not intended to define a unique structure, format, content or

method of presentation for the Quality Manual, which can be applied to all

(or even some) laboratories. It is unique to each laboratory. However, it is

recommended that the first few pages of the Quality Manual should

address to the sections of general information like title, authority under

which it is issued, scope of the Quality Manual, amendment record of the

manual, contents of the manual, references to other documents,

definitions and abbreviations used, distribution record, brief description of

the laboratory and the management system .

After these pages, should place the section on ‘Quality Policy and

Objectives’ of the laboratory. The Quality Policy is required to be stated

under clause 4.2 of management requirements. It is preferred that it is

placed after the introductory pages, since this is the basic objective, the

laboratory’s management system is designed to meet. The remaining

sections of the Quality Manual should describe all applicable elements of

the ISO/IEC 17025 or ISO 15189. The description of these sections of the

Quality Manual should be in a sequence similar to that of ISO/IEC 17025

or ISO 15189, as applicable. Other sequencing or cross-referencing, as

appropriate to the laboratory, is acceptable.




Thereafter the list of documents, records and forms maintained by the

laboratory should be placed. Any supportive data, to be provided should

be annexed at the last.

A brief explanation of these sections has been given below. These

sections, should preferably be sequenced in the manner as given below:

Title

The title of the Quality Manual should clearly indicate the name of the

laboratory to which the manual belongs. It should also indicate the issue

number, issue date, holders name and the copy number. A typical ‘title

page’ is shown at page 11.

Release Authorisation

The section on ‘release authorisation’ should indicate the authority under

which the Quality Manual has been released. The management

responsible for the implementation of Quality Manual, normally the Head

of the laboratory should authorise its release for usage. Each copy should

bear evidence of this release. A typical ‘release authorisation’ is shown at

page 12.

Table of contents

The table of contents of a Quality Manual should show the titles of the

sections within it and how they can be located. The numbering system of

sections, subsections, pages, figures, exhibits, diagrams, tables, etc.,

should be clear and logical. A typical ‘table of contents’ is shown at

page 14.




Scope and field of application

This section of the Quality Manual should clearly mention the compliance

to the applicable standard(s) and NABL documents. It should also define

the field(s)/ discipline(s)/ area(s) and the section(s)/ division(s)department(s) of the laboratory, to which the Quality Manual is applicable.

To ensure clarity and avoid confusion, the use of disclaimers (eg. what is

not covered by the Quality Manual and situations where it should not be

applied) may also be mentioned.

Use of references

Wherever appropriate, and to avoid unnecessary document volume,

reference to existing recognised standards or documents available with

the Quality Manual user should be incorporated.

Definitions

Although it is recommended, when practical, to use standard definitions

and terms which are referenced in recognised quality terminology

documents or in general dictionary usage, this section of the Quality

Manual should contain the definitions of terms and concepts that are

uniquely used within the Quality Manual.

The use of references to existing concepts, terminology, definitions and

standards (eg. ISO 8402) is highly recommended.

Abbreviations

Whenever the abbreviations are used, its expanded form should be

defined in this section.




Distribution of the manual

The method of distribution of the authorised manual should provide

assurance that all users have appropriate access. Proper distribution and

control can be aided, for example, by serialisation of copies for recipients.Management should ensure that individuals are familiar with those

contents of the manual appropriate to each user within the laboratory. A

typical ‘distribution record’ is shown at page 15.

Introduction

The introductory pages of a Quality Manual should provide general

information about the laboratory concerned and the Quality Manual itself.

The minimum information about the laboratory should be its name, site,

location and means of communication. Additional information about the

laboratory, such as its line of business, a brief description of its

background, history or size, may also be included.

The information about the Quality Manual itself should include:

a The current issue number, date of issue and identification of

amended contents

b A brief description of how the Quality Manual is revised and

maintained, who reviews its content and how often, who is authorised

to change the Quality Manual, and who is authorised to approve it,

this information may also be give under the system element

concerned; a method for determining the history of any change in

procedure may be included, if appropriate

c A brief description of the documented procedures used to identify the

status and to control the distribution of the Quality Manual, whether

or not is contains confidential information, whether it is used only for

the laboratory’s internal purposes, or whether it can be made

available externally




d Evidence of approval by those responsible for authorisation of the

contents of the Quality Manual.

Quality Policy and Objectives

This section of a Quality Manual should state the laboratory’s Quality

Policy and objectives, which should be in line with the requirements of

clause 4.2 of ISO/IEC 17025 or ISO 15189, as applicable. This is where

the laboratory commitment to quality is presented and where the

laboratory’s objectives for quality are outlines. This section should also

describe how the Quality Policy is made known to, and understood by, all

employees and how it is implemented and maintained at all levels.

Elements of the Management system

The subsequent sections of the Quality Manual should describe all the

elements of the ISO/IEC 17025 or ISO 15189 as applicable.

The format or method of presentation for the description of management

system elements, which can be applied, is unique to each laboratory.

However it is recommended that the description of the elements of the

management system be in a sequence similar to that of ISO/IEC 17025 or

ISO 15189, as applicable.

Further the description of each element should be divided into logical

sub-sections revealing a well-coordinated management system. This may

be done by inclusion of policy and objectives with respect to the element

or reference to the policy, scope, person(s)/ position responsible for

executing that policy, documented management system procedures and

reference to records for each element.

The management system procedure of each element of Quality Manual,

wherever applicable, should be briefly outlined, covering the major aspects

of respective clause of ISO/IEC 17025 or ISO 15189. The actual process/

procedure may be covered in separate procedure document and cross

referred in the Quality Manual.

and when the manual is amended, the relevant pages where amendment

takes place are replaced by new pages and is cross referred in the

amendment record. A typical ‘amendment record’ is shown at page 13. It

also gives the copy number. As and when each holder is issued a Quality

Manual, a copy no. is allotted to him/ her and this is indicated in the

distribution record, page 15. The signatures of the persons/ position who

have prepared, approved and issued the Quality Manual are also placed in
