Unlike standard kidney function tests, which often only show problems once damage has already occurred, this kit identifies stress at a much earlier stage by measuring Liver-type Fatty Acid Binding Protein (L-FABP) in urine.
L-FABP is a protein found in kidney cells that helps manage fatty acids. When the kidneys are placed under stress — such as from heat, dehydration, or reduced blood flow — they release L-FABP into the urine.
Rising levels of L-FABP provide an early signal of kidney stress, often before clinical symptoms or standard tests show any abnormalities. This allows for timely action to reduce the risk of acute kidney injury and long-term complications.
The HeatStroke Kit Test is intended for research use in populations working in high-risk environments such as the military, construction, oil & gas, and logistics sectors, where early detection of kidney stress is essential for protecting health and maintaining performance.

In extreme heat conditions, the body's cooling mechanisms can become overwhelmed, leading to heat stroke—a life-threatening condition that can cause organ damage, including acute kidney injury. The HeatStroke Kit Test provides an early warning system by detecting elevated L-FABP levels in urine, allowing for timely intervention before serious complications develop.
