It necessitates the test of surge immunity in electrical or electronic equipment. IEC 61000-4-5 defines test set-up, procedures, and classification levels. In particular, it standardizes the required surge voltage and current waveforms for laboratory testing, with the "1.2/50-8/20 μs" impulse being the most frequently used surge waveform.
For human urinary LH, one IU is defined as 1/189th of an ampule denoted 96/602 and distributed by the NIBSC, corresponding to approximately 0.04656 μg of LH protein for a single IU, but older standard versions are still widely in use.

The LH secretion most noticeable as a LH surge lasting 48 to 72 hours in the middle of the ovarian cycle. [3] Meiosis in the dominant follicle resumes and follicle ruptures shortly after the LH surge. [27] Ovulation can only occur if GnSAF is absent and the mid-cycle LH surge occurs. [3] [27]
In hematology, hemophagocytic lymphohistiocytosis (HLH), also known as haemophagocytic lymphohistiocytosis (British spelling), and hemophagocytic or haemophagocytic syndrome, [1] is an uncommon hematologic disorder seen more often in children than in adults.

It is commonly known that monthly surge of preovulatory LH from the pituitary gland promotes meiotic resumption. First, LH signaling dephosphorylates and inactivates NPR2 guanylyl cyclase. This results in a rapid decrease in cGMP levels in the granulosa cells and the oocytes through the gap junctions.
