The greatest percentage
What is the main reason why non-blood samples require additional care?
Because they are not as easy to get repeat samples in most cases and may be highly infectious
What is the importance of sound practices when dealing with non-blood samples?
To ensure safe handling and transmission of samples, and to obtain accurate results
What is the significance of non-blood samples in medical diagnosis?
They may provide extremely important information (life or death)
What is the general rule for handling all laboratory samples?
They must be handled as having the potential to transmit infection/disease
What type of non-blood sample is typically collected with the support of a surgeon?
Tissue biopsy (histological/cytological specimens)
What is the variety of non-blood samples based on?
The clinical condition/disease of the patient
What is the importance of understanding non-blood samples in phlebotomy?
To appreciate the complexity of medical conditions and the need for these samples
Study Notes
Laboratory Samples
- Laboratory samples can be of many different types, but blood samples make up the greatest percentage.
- Non-blood samples are a frequent part of almost all referral forms and require understanding of their common types in relation to phlebotomy.
Non-Blood Samples
- There are many different types of non-blood samples, which vary based on the clinical condition or disease of the patient.
- They require special handling and care, and can be routine, pre-op, post-op, or other types.
- Examples of common non-blood samples include:
- Urine samples (MSU, random, first morning, 24hr)
- Sputum samples (MCS/AFB)
- Stool samples (OBR/OCP/MCS)
- Semen samples (analysis, M/C/S)
- Swabs (all types)
- Histological/cytological specimens
- PUS, exudates, and fluids (such as synovial, pleural, and CSF)
Important Points to Note
- All samples must be handled as having the potential to transmit infection or disease.
- Non-blood samples require additional care, as they are not always easy to get repeat samples.
- Many non-blood samples can be highly infectious, and the results from these samples may provide extremely important information (life or death).
- Some non-blood samples, such as those requiring surgical support, may require special collection procedures.
