Australian Lab services has an offshoot called e-monitor, which does oil analysis. They supply the sample kit, cost $20, but for that price you won't get a TBN.
The Wearcheck analysis is handled by ALS, Australian Lab. Services, who also do the E-Monitor test as stated above. So it is the same lab, same equipment.
So if you want to pay extra for the Wearcheck service, you will get extra data. The $20 e-monitor service is enough for my needs.
Let us know the cost of the "full works", it will be a lot more than $20.
