Study Notes
- Proper diagnosis of infection is vital in microbiology and parasitology.
- It requires patient history, physical examination, evaluation of signs and symptoms, and appropriate clinical specimen collection.
Clinical Specimens
- Blood, feces, sputum, and wound specimens may be taken
- Urine, cerebrospinal fluids and throat swabs may be taken
High Quality Specimens
- High quality specimens are critical for accurate, clinically relevant laboratory results.
- They provide information to properly diagnose a patient's infectious disease.
Specimen Quality Components
- Proper specimen selection, collection, and transport to the laboratory are crucial.
Effects of Improper Collection
- The etiologic agent may be missed or destroyed if not taken properly.
- Indigenous microflora overgrowth can mask the pathogen.
- Contaminants can interfere with results.
Specimen Selection, Collection, and Transport:
- Specimens must be properly and carefully selected and collected.
- Collect material from the most likely site of the suspected pathogen.
- Obtain specimens ideally before starting antimicrobial therapy.
- The acute stage of the disease is the best for specimen collection.
- Collect specimens with care to avoid harming the patient.
- Get a sufficient specimen quantity for all required diagnostic tests.
- Use sterile containers to prevent contamination.
- Protect specimens from heat and cold, deliver them to the lab promptly.
- Handle hazardous specimens with extra care to avoid contamination.
- Use sterile/disposable specimen containers as much as possible.
- Specimen containers should be labeled properly.
Terminologies:
- Pathology is the study of the structural and functional manifestations of disease.
- A pathologist is a physician with extensive, specialized pathology training.
- Anatomical pathology involves pathologists performing autopsies and examining diseased organs, tissue sections, and cytology specimens.
- Clinical pathology includes blood bank, clinical microscopy, hematology, and immunology lab work.
Specimens for Bacteria

- Bone marrow, cervical & vaginal swab, feces & rectal swab, pus from wound, throat swab may be taken for specimens
- Sputum, urogenital secretion, and tissue specimen may be taken for specimens
Specimens for Virus
- Blood, conjunctival swab, and feces & rectal swab may be taken for specimens
- Bronchial washes, tissue specimen, and throat swab may be taken for specimens
- CSF and urine may be taken for specimens
Specimens for Fungi

- Hair clipping and nail clipping may be taken for specimens
- CSF and tissue specimen may be taken for specimens
- Skin scraping may be taken for specimens
Specimens for Parasite

- CSF and urogenital secretion may be taken for specimens
- Sputum and urine may be taken for specimens
- Feces/rectal swab may be taken for specimens
