The company said it has faced competitive pressures in its diagnostics business, partially offset by organizational streamlining efforts it initiated last year.
The company's revenues in the quarter rose to $221.9 million from $161.0 million in Q4 2017, but it missed the consensus Wall Street estimate of $245.3 million.
For the last three months of 2018, Invitae reported $45.4 million in revenues compared to $25.4 million in Q4 2017, beating the consensus Wall Street estimate.
The company will compete by continuing product improvements, ramping up marketing presence, and launching an app to improve doctor and consumer engagement.
The firm reported total revenu 16.8 million, up from $187.9 million in Q2 2018 and just above analysts' average estimate.
The company said it expects revenues from its ePlex analyzers to go up approximately 110 percent year over year for Q4.
The company's CEO noted softness in both its diagnostics and life science segment. The projected revenues would fall short of the consensus Wall Street estimate.
The firm expects Q4 revenues to be in the $132 million to $133 million range, up 15 to 16 percent from a year ago and consistent with the consensus Wall Street estimate.
The company expects to miss the consensus Wall Street revenue estimates for Q4 and full-year 2018.
In a preliminary financial report, the company said it is expecting revenues of more than $144 million and to have tested more than 300,000 samples.
