The legal representatives of the ongoing inquiry are due to make their closing statement today.
The inquiry is looking into how hundreds of people in Scotland received contaminated blood in the 1970s and 1980s.
In the first evidence session earlier this month Lord Penrose heard from patients and relatives in a closed session so they could give evidence anonymously.
Many in Scotland are thought to have received the blood contaminated by Hepatitis C.
At the end of the session no conclusions had been drawn and while Laura Dunlop, one of the four advocates thanked many involved, there is still a long way to go.
The evidence has now been collected and now time must be taken so there is time to reflect on the value of the material.
The victims will be given an explanation after a conclusion is drawn but it is a controversial issue and the number of people who have been affected need to be established.
There is a serious tone underlining the session with the closing statement claiming “they will not be happy to reach a final conclusion without all the stones unturned.”
