How to fill out QUALITY ASSURANCE IN SPUTUM SMEAR MICROSCOPY

1. Gather all necessary materials, including a microscope, slides, and reagents.
2. Prepare the sputum sample by ensuring it is properly collected and stored.
3. Stain the sputum smear using appropriate staining techniques, such as Ziehl-Neelsen or auramine-rhodamine stains.
4. Allow the stained slide to dry completely before examining it under the microscope.
5. Adjust the microscope settings for optimal viewing, including lighting and focus.
6. Carefully analyze the smear for the presence of acid-fast bacilli (AFB) or other relevant microorganisms.
7. Document and report findings accurately, ensuring that all results are recorded clearly.
8. Implement regular quality control checks and participate in external quality assurance programs.

What is the procedure of afb staining?

Procedure of Acid-Fast Stain Prepare bacterial smear on clean and grease free slide, using sterile technique. Allow smear to air dry and then heat fix. Alcohol-fixation: This is recommended when the smear has not been prepared from sodium hypochlorite (bleach) treated sputum and will not be stained immediately.

How to perform afb culture?

The AFB culture refers to the process of inoculating a clinical specimen onto culture media; including Becton-Dickinson Mycobacteria Growth Indicator Tubes (B-D MGIT broth) and a Lowenstein-Jensen (L-J) media slant. It is then incubated at 37°C for up to six weeks. Lastly, it is examined for growth or no growth.

What is the procedure of sputum for afb staining?

Your health care provider will need a sample of your sputum for all AFB tests. The AFB smear and AFB culture are usually done at the same time. To get sputum samples: You will be asked to breathe deeply and then cough and spit into a sterile container.

How can you determine the correct size and thickness of a sputum smear?

A good smear is spread evenly over a size of 2 cm × 3 cm and is neither too thick nor too thin. This was allowed to air-dry for 15-30 min and fixed by passing it over the blue flame of the bunsen burner three to four times.

What constitutes a good sample for sputum microscopy?

The quality of sputum samples is determined by the minimum number of squamous epithelial cells and polymorphonuclear leukocytes per low power field. An acceptable specimen has more than 25 leukocytes and fewer than 10 epithelial cells per low power field.

What is the procedure of sputum afb?

In this test, your sputum sample is "smeared" on a glass slide and looked at under a microscope. It can provide results in 1-2 days. These results can show a possible or likely infection but cannot be used to provide a diagnosis.

If you have trouble coughing up enough sputum, your provider may ask you to breathe in a salty mist to help you cough more deeply.

What are the limitations of sputum smear microscopy?

Sputum microscopy The main limitations of smear microscopy include its low sensitivity (50–60% in most studies), inability to allow species identification and drug susceptibility testing, and inability to distinguish viable from dead bacteria while monitoring the response to treatment.
