The main purpose of this Manual is to provide useful guidelines for the selection of pathology tests and to facilitate interpretation of results.
Contains a comprehensive listing of all genes from the Human Gene Nomenclature Committee (HGNC) database alongside laboratories and tests available in the country.
A manual for the process of macroscopic dissection in Anatomical Pathology laboratories.

Keywords: Pus microscopy culture sensitivities, Wound microscopy culture sensitivities, Wound MCS
Aspirate from collection, abscess or wound; biopsy of abscess wall. The specimen should be collected in a sterile container.
Pus should always be aspirated, if possible, rather than collecting a wound swab.
Swabs from a draining wound or sinus are frequently contaminated with normal flora from skin, mucous membrane.
Pus or wound swab (in transport medium) should be transported immediately to the laboratory.
Biopsy of abscess wall or adjacent tissue may increase the yield, especially in chronic infection.
Gram stain for microscopy.
Bacterial culture for aerobes and anaerobes.
Stain for acid fast bacilli and/or culture for mycobacteria and fungi is performed only if specifically requested.
Identification of pathogenic organism(s) to enable selection of the most appropriate management.
Presence of neutrophil polymorphs and bacteria in Gram stains of uncontaminated aspirates or swabs identifies likely bacterial infection.
Acid fast bacilli in pus or adjacent tissue biopsy suggests mycobacterial infection.
Nocardia spp may be acid fast with modified staining techniques.
Yeasts or hyphae suggest fungal infection.
