I will now turn the call over toCaren Mason for a quick status update on the impact the San Diego fire situation has had on Quidel. Caren?

Thanks, Don. And thank you toeveryone for joining us this afternoon. I'm sure all of you have been followingthe news reports of the wildfires in San Diegoover the last several days. In light of that situation, I want to provide youwith a brief update on how our business has been impacted. Most importantly, our employeesare safe and secure, although many have been displaced from their homes due tomandatory evacuations in the San Diego County. We have had a skeleton crewat our San Diego facility sinceMonday of this week ensuring customers' orders are fulfilled from ourfinished-goods warehouse in the Los Angelesarea. Our inventory levels have beenable to meet demand, and we are shipping daily. We anticipate that productionwill be at full throttle in the next few days. It is important to note that wehave been cognizant of the need to meet public health demand for our upper respiratorytests, and we have worked diligently to get the job done. We expect to have our San Diego facility fully functioning by the beginning ofnext week at the latest, and this temporary disruption should not impact ourability to meet customer demand in the fourth quarter. My thanks to ouremployees, suppliers and distributors for their excellent performance andpartnership during this very challenging time. And now, John will present ourfinancial results for the third quarter. John?

Thanks, Caren, and hello toeveryone on the call. We are pleased with the performance of the business thisquarter, as we've posted another quarter of double-digit revenue growth. Includingthis quarter, we have delivered seven consecutive quarters of double-digit organicrevenue growth. And just as significantly, our operating margins expanded 520basis points, for the third quarter of 2007 compared to the same period of lastyear. Starting with the top line. Totalrevenues for the third quarter were $27.6 million, a 16% increase over thethird quarter a year ago. This growth was driven by strong sales of ourinfectious disease tests, in particular, domestic sales of the QuickVueInfluenza Test in advance of the upcoming flu season. Our gross margin in the 2007 thirdquarter was 60%, compared to gross margin of 56% in last year's third quarter.The improvement was mainly attributable to a favorable product and geographicmix. Operating expenses for the thirdquarter of 2007 grew 11% to $12.7 million. The increase was primarily in salesand marketing, reflecting the personnel additions we made at the beginning ofthis year and capabilities within our sales group to address expanded marketopportunities as well as higher intangible amortization related to licenses atthe end of last year. Operating income grewsignificantly from $2 million in the third quarter of 2006 to $3.7 million thisyear, an increase of 87%. Net income for the third quarter was $2.4 million or$0.07 per share fully diluted compared with a net income of $2.1 million or$0.06 per share fully diluted for the third quarter of 2006. Just to remind everyone, lastyear, tax expense in the third quarter was zero. For comparison purposes, hadwe recorded tax expense in 2006 at the same rate as this year, our EPS lastyear would have been approximately $0.04 per share. Our balance sheet remains verystrong. Cash and cash equivalents as of the end of the third quarter were $35.3million compared to $36.6 million at December 31, 2006. Year-to-date, we have repurchased approximately 1.5million shares for $17 million. I'd also like to take a couple ofminutes to discuss trailing 12-month data and comparisons. I believe thisinformation is more revealing of our annualized strength, as the trailing12-month numbers put in perspective the quarterly seasonality of the business. Trailing 12-month revenue ending September 30, 2007 was $118.9 million,up 17% over the comparable trailing 12-months ended September 30th 2006. Our gross margin in thetrailing 12-months improved from 58% to 59%. And most importantly, ouroperating profit in the trailing 12-months was $19.2 million, an increase of47% over the prior 12 months. This performance reflects the leverage in ourbusiness model, and the strength of our QVB strategy, which has provided thefoundation for our growth. And now I will turn the call overto Caren for a review of the key strategic accomplishments and developments inthe quarter. Caren?

Thank you, John. We're pleased tobe presenting the results of another strong quarter, trailing 12-months, andprogress in several aspects of our business. I do want to reinforce one of thekey areas John highlighted, which is the continued improvement in operatingmargin. I believe this improvement is directly related to the success ofvarious elements of our QVB strategy, which we are leveraging across a growingcustomer base and into new markets. These elements include the strongclinical research support for our tests, our outstanding go-to-market strategyand technical support programs and a leading brand name that signifies qualityand enables partnerships with leading diagnostics and pharma companies. Anumber of the developments in the third quarter and subsequent to the close ofthe quarter, demonstrates the strength of QVB in building our business andgrowing shareholder value. Before I get to those highlights,I want to mention that our most recent success was noted by Forbes as itincluded Quidel as 82nd on its list of America's200 Best Small Companies for the first time, in 2007. I'm particularly pleased atachieving this recognition as the criteria for inclusion included return on equityperformance, sustained sales growth and net profit growth. In addition, Forbesrecognized Quidel in a 10-company category designated as "Safe Bet"for efficient companies with little or no debt and a solid board of directors. All of these measurements reflectsignificant value creation for shareholders. This positive attention is atribute to the hard work and dedication of everyone at Quidel. Moving on to a review of thequarter, our strong results were driven by the planned performance of ourinfectious disease test group, which had sales growth of 29% over the thirdquarter of 2006 and growth of 25% year-to-date. More specifically, we saw verystrong demand for our influenza test in the U.S.,and the initial sales of our RSV test in acute-care facilities. We believe third quarter…

(Operator Instructions). Onemoment, please, for our first question. Our first question comes from ZarakKhurshid with Caris & Company. Zarak Khurshid - Caris & Company: Hi, Caren. Hi, John. Greatquarter. And best wishes to the Quidel family there in light of the fire.

Thank you.

Thank you. Zarak Khurshid - Caris & Company: So, first question. Could youbreak out, perhaps, the split of the big three products? Or their growth rates?

We're not splitting out the bigthree anymore. We talked about infectious disease and reproductive and women'shealth and other products. So I can tell you that the infectious diseasebusiness grew 29% in the quarter. And that was $18.6 million. Reproductive andwomen's health declined 6% to $5.9 million. And other products came in at $3.1million, a growth of 2%. Zarak Khurshid - Caris & Company: Okay. And then could you perhapsquantify the acute-care market for flu testing? And maybe perhaps give us someinsight as to how well penetrated that is today and maybe a split of your flubusiness, acute versus physician office? Then I'll jump back in the queue.Thanks.

Thanks, Zarak. We believe thatthe acute-care market is growing. We've seen a lot of interest in our flu testsas we've really amassed an exceptionally strong effort this year with ourdistribution partners to go after large, acute-care systems, integrateddelivery networks and others. We had that very niceannouncement about the Adventist Health System, which we're excited about. Andthere are others where we have been awarded a dual-source or letter ofcommitment. That give us some real excitement about what we'll be able to talkabout in the quarters to come, with regard to new users of QuickVue A+B testsand our RSV tests. With regard to splits, we believethat that acute-care segment for us will grow dramatically in this season, certainlyin excess of 30, 35% or more. Our target's way above that; of course, we alwaysgo for the gold. But we're confident that we're going to continue to grow theacute-care split, get more conversions as we do more of these great clinicalstudies. We're getting a lot of interestas a result of what we're reporting about the proper use of anti-virals, thestopping of the improper prescribing of antibiotics. We know how difficult thatprocess is today with so many bacterial infections being resistant with theimproper diagnosing of antibiotics. So just all of the arrows are pointing upfor the market to expand for both POL, acute-care, and also alternate marketsites, retail clinics, etc.

Your next question comes fromKeay Nakae with Collins Stewart.

Yes. Hi. This is actually DrewTeufel for Keay.

Hi, Drew.

How are you?

Good.

Just a couple questions aboutinventory levels at distributors; can you give us any color on that or wherethose levels are at?

Well, the distributors are in processin the fourth quarter, making sure that all of their customer base and allthese new converted customers have tests on the shelves appropriately, as westart to see influenza at this time. We know that there is influenzasporadically across the country, and some areas are experiencing more regionalinfluenza. So we don't have a full look fromdistribution for this stocking time until we get to about mid-quarter or to theend of the quarter. But our belief is that we're going to have a quick movementof that inventory, and we will continue to replenish throughout the end of thisyear.

Okay. And just switching over tothe FOB, any word on the timing of the clinical data from the study on that?

We'll have that ready by the endof the year and report on that in Q1 of '08.

Okay. Great. Thanks.

Thank you.

Thank you.

(Operator Instructions) Your nextquestion comes from Steven Crowley of Craig-Hallum Capital Group.

Good afternoon, folks.

Good afternoon, Steve.

Hi, Steve.

A couple questions for you. Youmentioned your significant pending or your objective for there to be a significantinvestment in R&D. In the quarter, R&D was flat year-over-year, probablya bit less than we had expected. It appears you're telegraphing a moreambitious effort there, and I'm wondering if you could give us a sense for howmuch more money you might be spending there and your priorities in R&D.

Sure. I think, Steve, I'll startwith our priorities in R&D. We are really focusing on an enhancement to ourcurrent technology. And instruments may be part of that enhancement. We alsohave a team of people that are working on molecular systems and solutions toexploit our worldwide ownership of the MChip and Flu Chip technology. And wealso have a team of people that are looking at alternate market development anddesign, including OTC. So there is a lot going on in terms of expansion. Withregard to percent of revenue, I'll turn it over to John for a discussion.

Yes. Steve, I think we'retargeting R&D to be in the 11 to 12% of revenue range on a trailing12-month or annual basis. There could be quarters in which that might spike up,depending upon the kind of activities that we might be doing in the quarter.

Yes. I think just to add one note,there has been some delayed spending, and that, we believe, will pick up againin Q4 and Q1, of course, and into '08.

Okay. Excellent. In terms of anupdate on iFOB, what can you tell us about signs of market traction or anyevidence about growing traction around iFOB? And an update on yoursecond-generation tests. And as part of my follow-up,maybe, John, just a bookkeeping item or two about the balance sheet, accountsreceivable and inventories at the end of the period? Thanks.

Okay. On iFOB, we are continuingto see, and gladly so, more studies being published that support the use ofimmunochemical over guaiac. We believe that the iFOB test will definitely havetraction over the months and years to come as a first line defense forscreening over today's guaiac. Our generation-2 product is veryexciting. The design and the development of that product is meeting andexceeding our targets. We are confident in that product in its opportunity andability to delight end users, the patients themselves, the physicians who will prescribethem and any lab services companies who want to work with us as well. We believe we have some veryunique ways of delivering the products and services around the iFOB products,so that that along with outstanding marketing, distributor partnerships andreally good end user, consumer based advertising and education in the springwill set us up perfectly for Q2 of '08. I'll turn it over then to you,John, with regard to Steve's other questions.

So, with respect to the balancesheet, receivables at the end of September of '07 stood at roughly about $17million versus $18.1 million at December of '06. And inventory stood at $11.6million at the end of the quarter versus $9.6 million at the end of the prioryear.

Great. Thanks for taking myquestions. I'll hop back in the queue.

Thanks, Steve.

Thanks, Steve.

That is all the time we have,today. Please proceed with your presentation or any closing remarks.
