What this card shows
The hCG positive test rate for PGT tested embryos card follows genetically tested embryos through to their pregnancy test result, month by month.
Two pieces of vocabulary first, because both are in the card title. hCG is the pregnancy hormone, and a positive hCG test is the first sign that a transfer has taken. PGT-A is preimplantation genetic testing for chromosome number: a small sample, called a biopsy, is taken from the embryo and sent to a genetics lab, which reports whether the embryo has the expected number of chromosomes (euploid) or not (aneuploid).
An embryo counts on this card if it went through a biopsy where PGT-A was one of the tests requested. Each embryo is placed in the month its biopsy was requested, not the month it was transferred, so a single point groups together the embryos your lab biopsied in that month.
There are two lines, and they measure different things:
Positive hCG test rate, the solid line on the left-hand axis. Of the tested embryos from that month that were transferred and have a pregnancy test result recorded, whether positive or negative, this is the share that came back positive.
Embryos awaiting outcome data, the dashed line on the right-hand axis. A count, not a percentage: tested embryos from that month for which neither the genetics result nor any pregnancy test result has come back yet. This is your in-flight pipeline.
Reading the card
The rate covers all tested embryos that were transferred, whatever the genetics result said. In practice clinics transfer euploid embryos and rarely transfer aneuploid ones, so in most months the figure is effectively a euploid transfer result. But the card does not separate them, so please do not read it as a euploid-only success rate. A breakdown by chromosomal result is a possible future addition to the card.
The dashed line is a count of embryos, on its own axis. Both vertical axes carry the same label, so use the legend at the top of the card, rather than the axis titles, to tell the two lines apart. A high dashed line means work in progress, not work gone wrong: those embryos are simply still waiting on a genetics report, a transfer, or a pregnancy test.
The most recent months are incomplete by design. A biopsy taken this month cannot have a pregnancy test result yet, so the recent end of the solid line rests on very few embryos and the dashed line rises. A run of declining recent months alongside a spike in the awaiting count is the normal shape of reporting lag, not a fall in performance. Wait for the pipeline to clear before reading anything into it.
Monthly numbers here are small. A handful of transfers is enough to move the rate by tens of percentage points, so single-month movements are noise. Hover any point to see the counts behind it, and look at the direction over several months rather than at one point.
Only embryos with a pregnancy test result recorded are in the rate. An embryo that was transferred but whose result was never entered is in neither the numerator nor the denominator, so it does not count against you, but it does not count for you either.
The card lives on the Medical director dashboard, on the Clinical success tab, and responds to the filters at the top:
Date: change the time window. It scopes by the date the biopsy was requested, and defaults to the past 6 months plus the current month.
Clinic: focus on one or more locations, if your organization has several.
Age at cycle start and BMI: narrow to a patient group.
Where this data comes from
Both halves of this card are entered on the patient's Cycle page.
The biopsy comes from the Culture tab, where the lab records what happened to each embryo. Selecting an embryo and using the Biopsy action is what puts it on this card, and the genetics test requested is noted on that biopsy. An embryo only appears here if the biopsy was recorded with the genetic test noted against it, so a biopsy logged without it will be missing from the card entirely.
The pregnancy test result comes from the Outcomes tab of the same Cycle page, through the Add Outcome menu.
Choosing one of the hCG options opens a short form where the hormone value and the positive or negative pregnancy test result are entered.
The rate can only reflect results that have been entered. Where the card looks lower than you expect, unentered pregnancy tests are the first thing to check, followed by biopsies recorded without the genetic test noted.
