Total lactate dehydrogenase (LDH) activity varies significantly with age, particularly in children. Socio-professional status also influences LDH levels, while adult morphology shows minimal impact on this enzyme
Area of Science:
Biochemistry
Clinical Chemistry
Human Physiology
Context:
Establishing reference intervals for enzymes is crucial for accurate clinical diagnosis.
Lactate dehydrogenase (LDH) is a key enzyme in cellular metabolism with diagnostic relevance.
Understanding factors influencing enzyme activity is essential for interpreting laboratory results.
Purpose:
To determine reference intervals for total lactate dehydrogenase (LDH) activity in a large population.
To investigate variations in LDH activity based on demographic and lifestyle factors.
To identify key determinants of LDH levels in diverse individuals.
Summary:
Frequent values for total lactate dehydrogenase (LDH) activity were established from a population of 87,600 individuals.
Reference intervals were defined, and variations were analyzed concerning age, sex, body morphology, socio-professional categories, excess weight, exercise, and drug use.
Significant variations in LDH activity were observed with age, especially in children, and notably influenced by socio-professional groups, with minimal impact from adult morphology.
Impact:
Provides essential reference data for clinical laboratories and healthcare professionals.
Highlights the importance of considering age and socio-economic factors in LDH level interpretation.
Contributes to a better understanding of lactate dehydrogenase (LDH) enzyme kinetics in human populations.
