What is the stability duration of lactate dehydrogenase (LD) at room temperature?

Lactate dehydrogenase (LDH) is an enzyme that plays a key role in anaerobic metabolism, and its stability is important for accurate laboratory results. At room temperature, LDH can typically maintain stability for about 2 days. This duration is significant for laboratory practice, as it allows for samples to be processed without the need for immediate refrigeration or special handling for that time frame.

Understanding the stability of LDH at room temperature is crucial for laboratories to establish protocols around sample processing and storage. If samples are going to be delayed in processing, knowing that LDH can remain stable for up to 48 hours helps technicians make informed decisions about sample management.

In comparison, other durations such as 24 hours, 1 week, or even longer periods are generally not accurate for LDH, as enzyme activity can significantly decrease beyond the stated time frame. Knowing the correct stability period is essential for ensuring that laboratory results reflect true patient conditions accurately without degradation of the analyte.
