13. Laboratory analysis of plasma enzymes
- Enzymes
- Measurement based on enzyme activity
- Enzyme + substrate ->
- coloured product -> photometry
- or a secondary reaction which forms a coloured product -> photometry
- or there is a change in NADH -> photometry with UV light
- 1 unit = 1 µmol substrate per minute
- U/L = µmol/min/L
- Most frequently measured enzymes
- ASAT
- ALAT
- GGT
- ALP
- LDH
- CK
- Amylase
- Lipase
