GUIDELINES

DEVELOPMENT OF STANDARD PRACTICE PROCEDURE IN MANAGEMENT OF LABORATORY QUALITY
(
Issued with Decision No. 5530/QD-BYT dated 25/12/2015 of the Minister of Health)

 

INTRODUCTION

In recent years, the management of laboratory quality has received the special attention and steering from the Ministry of Health to improve the capacity of laboratory system, ensure the laboratory result is accurate, timely, avoid waste and save money for patients. In 2013, the Ministry of Health issued the Circular No. 01/2013/TT-BYT on “Guidelines on development of standard practice procedure in management of laboratory quality are applied at the medical facilities” specifying that all units must develop the standard practice procedure. This is one of the important tasks in management of laboratory quality to ensure the work is done consistently and the laboratory result is standardized and accurate.

For the time being, a lot of units have implemented the above Circular. The laboratory quality is constantly improved and better controlled. However, there are in fact laboratories at medical facilities with standard laboratory procedures but incomplete, inconsistent and without high efficiency; there are also laborotories having inadequate or no standard laboratory procedures in prescribed quality management. The above problems are due to many causes and one of them is that there are officers, managers and persons performing laboratory work not understand the role and importance of compliance with the standard laboratory procedures in management of laboratory quality.

Therefore, the requirement laid down is to standardize and provide complete, detailed and systematic guidelines in developing the standard laboratory procedures in management of laboratory quality, providing assistance in assessment and examination of laboratory results and monitoring in a objective manner to ensure the laboratory result. The issue of guidelines on compiling the standard practice procedure in management of laboratory quality is very necessary.

The content of the Guidelines includes 03 chapters and annex 1 and 2, specify name and sample examples on standard practice procedure in management of laboratory quality.

This is the first time there is a complete guideline on developing the standard practice procedure in the management of laboratory quality. Therefore, the shortcomings are inevitable. The Ministry of Health (Agency of Medical Services Administration) is looking forward to receiving the comments from the units, individuals and experts to so that this Guideline material is increasingly improved with better quality in order to contribute to the highest benefits for patients.

Procedure for direct sputum testing for Acid Fast Bacilli (AFB) by Ziehl-Neelsen stain

XX Laboratory Department

Version 1.0

Document code: XX-QTKT-06

1. Purpose

- Describe and guide the way to do the direct sputum testing for Acid Fast Bacilli (AFB) by Ziehl-Neelsen stain.

2. Scope

- To be applied at XX Laboratory Department - XYZ General Hospital

3. Responsibility

- The officer assigned to do this test must properly comply with the procedure.

- The quality controller and professional team leader must monitor the compliance with procedure and assess the laboratory result.

4. Definition and abbreviation

AFB

Acid fast bacilli - Alcohol and acid resistant bacilli of Mycobacteriaceae family

BCĐN

Monocyte

ZN

Zeihl-Neelsen

 

5. Principle

The Ziehl-Neelsen stain is the method using 02 staining chemicals as fuchsin red and methylene blue combined with decolorant (mixture of HCL acid and alcohol 96 °) for detection of AFB. This method is used to detect the microorganisms of Mycobacteriacae family as microorganisms with alcohol and acid resistant characteristics. They can survive in the environment with certain alcohol or acid content without losing their color when bleached with alcohol or acid

6. Equipment and material

6.1. Equipment

- Compound optical microscope with objective lens 100X, 10X

- Biosafety cabinet class 1

- Minute timer

6.2. Material

6.2.1. Devices

- Glass slide with translucent head

- HB pencil

- Plastic cup for containing sputum

- Disposable sputum smear spatula

- Specimen stain rack

- Microscope cleaning tissue

6.2.2. Chemical

- Fuchsin solution 0,3%

- HCL alcohol solution 3%

- Methylen solution 0,3%.

- Phenol antiseptic solution 5% or Javen 0.5%

- Immersion oil

6.2.3. Specimen:

- Sputum contained in a sterile clean plastic tube with lid.

7. Safety

- Apply the general safety measures when processing and testing the specimen under the procedure for laboratory safety with code XX-QTQL-10.

8. Implementation procedure

8.1. Preparation

- Start up the biosafety cabinet at least 15 minutes before implementation.

- Arrange necessary devices in the biosafety cabinet.

- Choose the clean and unscratched glass slide. Dry the slide over the flame of spirit lamp to eliminate the oil on it and leave it cool.

- Use HB pencil to write the code of specimen on the translucent head of glass slide.

- Arrange the sputum container and glass slide in order to avoid confusion.

Note: The testing number must be consistent between the testing number, testing slip, sputum container and glass slide.

8.2. Specimen spreading:

In the biosafety cabinet:

- Gently open the lid of sputum container, put the cap on its back on the stainless steel tray.

- Use the beveled head of spatula to smear the sputum and gently cut it by wiping the beveled side of spatula on the sputum container wall (note: use each spatula for each specimen)

- Close the sputum container.

- Put the spatula with specimen in the middle of slide and spread under the spirals from the inside out regularly and continuously to form an oval shape with size of 2 cm long and 1cm wide with the fineness and moderate thickness.

- Soak the spatula after spread into the antiseptic phenol solution 0.5% or Javel 5%.

Note: Only discarding the sputum container after returning the testing result.

8.3. Specimen drying

- Put the specimen on the glass tray and leave it dry completely at the room temperature (18-25°C).

Note: Do not dry the specimen with spirit lamp or in the sun light.

8.4. Specimen fixing:

- Do it outside the biosafety cabinet.

- Dry the specimen from side to side over the flame of spirit lamp for 3-4 times, 3 seconds for each time.

Note: Do not fix the specimen if it is not dry completely.

8.5. Staining

- Put the specimen on the staining rack

- Cover Fuchsin solution 0,3% on the fixed specimen smear side.

- Dry it over the flame of spirit lamp until evaporation (do not leave it boil) for 1 time.

- Leave it cool naturally in 5 minutes.

- Rinse it under light running water.

8.6. Decoloring

- Cover HCL alcohol solution 3%

- Leave the specimen in 3 minutes.

- Rinse it under light running water.

Perform the 2nd discoloring (1-3 minutes) if the specimen is still pink

8.7. Base staining:

- Cover the Methylen solution 0,3% in 1 minute.

- Rinse it under light running water (note: do not put the specimen directly under strong running water).

- Leave it dry at room temperature.

8.8. Result reading:

- Examine the specimen with optical microscope with oil objective lens 100X as instructed in the manual for microscope with oil objective lens code XX.HD.03.

+ Positive: AFB is rod-shaped bacilli that are thin, somewhat curved, Fuchsin red absorbing, individually, in pairs or groups on blue background.

+ Negative: No AFB found

9. Quality control:

There are 06 standards as follows:

9.1. Specimen quality:

- Observation: specimen has no mucus, saliva and blood at best.

- Standard upon microscopic examination:

+ There are 25 polymorphonuclear leukocytes (examination of objective lens 10X, eyepiece 10X).

+ There are 3-4 polymorphonuclear leukocytes/microscopic field (examination of objective lens 10X, eyepiece 10X).

+ Or there are macrophages.

9.2. Size of specimen on glass slide

- Oval shape in the center of glass slide.

- 1cm wide and 1cm long.

9.3. Fineness

- The surface of specimen has the continuity, regularity without hollowness or flaking.

- Examination: The microscopic fields have the continuity and there are not many hollow microscopic fields, regular brightness.

9.4. Thickness

- The thickness of specimen is 0.04mm. Check by the way when the specimen is dry without staining, put a paper with letters 4-5 cm away from the specimen.

+ Satisfactory: if the words are fuzzy and readable.

+ Too thick: Illegible

+ Thin: Unclear

- Examine the depth of the specimen (bright blue microscopic field).

- If the specimen is too thick: Many layers, the microscopic field cannot be examined (dark blue microscopic field).

- If the specimen is too thin: Microscopic fields are sparse (light blue).

9.5. Staining and discoloring:

- Examination under microscope: AFB absorb red color clearly on blue background.

- Unsatisfactory: The specimen is still red with naked eyes.

9.6. Cleaniness:

- No dirty residue, Fuchsin residue, crystal… upon examination under microscope.

- If there are dirty residues, the reasons are the stain is left long or dried too long during the staining.

9.7. Method of testing:

- Frequency of testing: daily or at least 1 week/1 time.

- Testing with a positive specimen to count the amount and color of AFB.

- Testing with a negative specimen to check if the stain and water source are infected with AFB.

- Write the result in the quality checking book.

10. Result interpretation and report:

Amount of AFB

Result

Classification

No AFB/100 microscopic fields

Negative

With AFB > 10 AFB/ 1 microscopic field

(Examination of at least 20 microscopic fields)

Positive

AFB 3 (+)

With 1-10 AFB/1 microscopic field

(Examination of at least 50 microscopic fields)

Positive

AFB 2 (+)

With from 10-99 AFB/100 microscopic fields

Positive

AFB 1 (+)

With from 1-9 AFB/100 microscopic fields

Positive

Write the amount of AFB/100 microscopic fields

Note: 01 line of glass slide is equivalent to 100 microscopic fields. Examine at least 3 lines.

11. Note:

- If AFB is light, it is because the discoloring was too long or the staining was not done sufficiently (time, heat).

- If AFB is dark, it is because the staining was too long.

- Each batch of stain should not contain 12 specimen which are placed at least 01 cm from each other.

12. Dossier storage

- Write the result in the result answer sheet and the sputum testing result book for AFB.

- Keep the forms of QC sheet in accordance with regulations of Department
