SAMPLE COLLECTION
PROCEDURE
1. Bacterial
2. Viral
3. Fungal
4. Protozoan
Bacterial such as:
o Streptococcus pyogenes
o Mycobacterium tuberculosis
o Salmonella typhi
o Vibrio cholerae
o Helicobacter pylori
o Staphylococcus aureus
o Bacillus anthracis
o Clostridium tetani
Sample collection of various type
of bacterial disease:
Blood tests including
• Total white blood cells and differential leucocytes’ counts.
• C- reactive protein (CRP) assay – Reading is >50 in serious bacterial
infections.
• Procalcitonin- It is a marker of generalised sepsis.
• Serology
• Observation of any bacilli in blood smear.
 Rountine urine examination : In UTI increase in pus cells.
 In Mastitis cases, slide tests for subclinical mastitis.
 For Faecal samples, low grade fever, straining and stomach cramps
and or loose stool for long duration.
Collection of blood
• At high fever stage.
• Multiple blood sample (2-3)
• From different veins.
• Local disinfection .
Viral such as:
o Polio
o Hepatitis
o Rabies
o Dengue
o AIDS
o Swine flu
o Ebola
o SARS
o COVID-19
Sample Collection of various type
of viral disease:
 CSF (Cerebral Spinal Fluid)
• A CSF is a laboratory test to look for bacteria,
fungi, and viruses in the fluid that moves in
the space around the spinal cord.
• Collect in sterile container. Do not dilute in
universal transport media(UTM) maintain
2-8˚C before and during transport to the
laboratory.
 Stool test : Collect 5-10 grams of stool in
clean container. Maintain at 2-8˚C before and
during transport to the laboratory.
Fungal such as:
o Athlete’s foot
o Candidiasis
o Blastomyosis
Sample Collection of various types of fungal diseases :
 Specimens for fungal microscopy and culture are transported to the laboratory in
a sterile container or a black paper envelope.
They include :
• Scrapings of scale, best taken from the leading edge of the rash after the skin has
been cleaned with alcohol.
• Skin stripped off with adhesive tape, which is then stuck on a glass slide.
• Hair which has been pulled out from the roots.
• Brushings from an area of scaling in the scalp.
• Nail clippings or skin scraped from under a nail.
• A skin biopsy.
• A moist swab from a mucosal surface (inside the mouth or vagina) in a special
transport medium.
Hair Specimens:
•Pluck hairs from the affected area using tweezers.
•Scrape the affected area using a scalped (held on a blunt
angel), on to a piece of paper.
•If available, examination of the scalp with a wood’s lamp
can guide the collection of samples from affected areas.
Protozoan such as:
o Malaria
o Kala- azar
Sample collection of varius type of protozoan
disease:
• Stool sample collection – Stool sample
collected on separate days, be examined.
• This test looks for ova (eggs) or the parasite.
Your health care provider may instruct you to
put your stool specimens into special
containers with preservative fluid.
