Bovine Post-mortem Magnesium Testing

Vitreous humor is an excellent sample to submit for post mortem suspect hypomagnesemia cases. The sample is collected as described above, only a deeper needle penetration is required for vitreous sampling. It is important to collect vitreous and not aqueous humor as the magnesium in the vitreous humor is more stable than that present in the aqueous humor.

Samples remain stable up to 48 hours after death.

Vitreous humor magnesium level should not be used as the only diagnostic test for hypomagnesemia. Clinical signs, diet, gestation period, etc. in addition to the magnesium level should be taken into consideration.
