What this card shows
The Donor oocytes used, by consent remaining at use card shows how many donor oocyte devices were thawed for treatment each month, grouped by how much of the storage consent was still to run on the day of the thaw.
It is the counterpart to the Donor oocytes in stock by consent expiry card beside it. That card shows what is approaching expiry; this one shows whether you are using material before it gets there. A rising Under 3 months left line means stock is being used late, and any Used after expiry at all is worth investigating.
The card counts devices, not oocytes. One cryotop commonly holds several oocytes, so the number of oocytes is usually higher.
Only devices recorded as donated count. A donor's own samples, thawed for their own treatment, are not counted.
Reading the card
Each line is one group: More than 12 months left, 3 to 12 months left, Under 3 months left, Used after expiry or No expiry recorded. Each point is the number of devices in that group thawed for treatment that month. Hover over a point to see its count. A group with no devices in the period has no line.
No expiry recorded means neither the device nor its sample has an expiry date recorded.
The dashboard's Date filter sets the months shown, by the date of the thaw. It defaults to the past 12 months, including the current month.
The Clinic filter narrows the chart to the clinics you choose. Here, clinic means the site the storage tank belongs to, so a device counts toward the clinic where it was stored before it was thawed.
Where this data comes from
A device counts as used when it is thawed from its sample in Cryostorage with the thaw's Reason set to Treatment. The month comes from the thaw's Thawed at date. Thaws for any other reason, such as a discard, research, training or a test thaw, are not counted.
The consent remaining is the time from the thaw to the Expiry date on the storage device, on the sample's edit page. If a device has no expiry date of its own, the sample's Expiry date is used instead.
A device counts as donated when, on the sample's storage devices, its Freeze purpose or Use status is set to a donation value: Donation or Known donation for the freeze purpose, Donation or Donated to bank for the use status. A donor's device frozen without a donation value is treated as the donor's own sample and is not counted.
Opening this card
