What are the contents of a lab report?

- demographic details from request
- results from lab analysis
- references ranges from scientific knowledge
- comments and advice from experience (human and computer knowledge bases)

List strategies to improve test

- select a more 'normal' population
- use a combination of tests (eg. LFT profiles)
- combine tests to achieve a diagnostic goal eg. neonatal screening for PKU and hypothyroidism
- sensitive first line test (low cost)
- specific test for screen positives (higher cost)

What are the appropriate 'normal' populations?

- patients with similar presenting symptoms eg. chest pain
- same age
- same gender
- hospitalised 'normals'
- same underlying disease

List some factors that affect reference ranges

- age
- gender
- diet
- pregnancy
- time of month
- time of day
- time of year
- weight
- stimulus

(must bear in mind when interpreting results)

Glycosylation of protein leads to what?

Advanced glycosylated endproducts (AGE)
- non-enzymatic process
- rate of formation proportional to glucose concentration and time
- may explain long-term compilations of diabetes

What is HbA1c?

Stable glycosylated haemoglobin
- its percentage concentration indicated cumulative glucose exposure

What are the contents of a lab report?

- demographic details from request- results from lab analysis - references ranges from scientific knowledge- comments and advice from experience (human and computer knowledge bases)

List strategies to improve test

- select a more 'normal' population- use a combination of tests (eg. LFT profiles) - combine tests to achieve a diagnostic goal eg. neonatal screening for PKU and hypothyroidism - sensitive first line test (low cost) - specific test for screen positives (higher cost)

What are the appropriate 'normal' populations?

- patients with similar presenting symptoms eg. chest pain - same age- same gender- hospitalised 'normals'- same underlying disease

List some factors that affect reference ranges

- age- gender- diet- pregnancy - time of month- time of day- time of year- weight - stimulus (must bear in mind when interpreting results)
