OPINION
Plaintiff-Appellant Michael Sutton appeals the November 26, 2003 order of the district court granting Defendants St. Jude Medical S.C., Inc.’s and St. Jude Medical, Inc.’s motion to dismiss for lack of standing. For the reasons set forth below, we REVERSE the district court’s order, and REMAND the case to the district court for further consideration.
I. INTRODUCTION
Plaintiff-Appellant Michael Sutton brought suit on behalf of a proposed class of persons who underwent cardiac bypass surgery using a medical device called the Symmetry Bypass System Connector (“device”). Heart surgeons use this device during cardiac bypass surgery to attach saphenous vein grafts to the aortic surface of the heart without sutures. Sutton was implanted with the device during treatment for his heart condition. Defendants-Appellees St. Jude Medical, S.C., Inc., and St. Jude Medical, Inc. (collectively “St. Jude”) are the designers, manufacturers, and distributors of the device. Sutton alleges that St. Jude failed to use reasonable care and was negligent in designing the device, and further, that the device is defective and unreasonably dangerous, and is sold and marketed without proper warnings. In addition, Sutton specifically alleges the following facts in his complaint:
(1) the device has “led to severe and disabling medical conditions resulting from collapse and scarring of the graft” in “numerous patients,” necessitating removal of the device and/or monitoring for further harm, including death (Complaint at 6, ¶ 15; Joint Appendix at 10);
(2) St. Jude was informed of adverse consequences associated with the device through incident reports from cardiac surgeons, but despite these warnings, St. Jude continues to market and distribute the aortic connector (Compl. at 6, ¶¶ 16-17; J.A. at 10);
(3) as a result of having this allegedly defective and unreasonably dangerous device implanted in him, Plaintiff “has suffered economic losses and large medical expenses and has a device in his body which increases his risk for aortic bypass stenosis or occlusion and its resulting physical injuries” (Compl. at 6, ¶ 29; J.A. at 10).
Sutton brought a diversity suit on behalf of all persons in whom the device has been implanted. 1
Sutton, on behalf of the putative class of persons implanted with the device, seeks the imposition of a medical monitoring fund providing the following: (1) notice to all persons implanted with the device of its potential harm; (2) periodic medical examinations, including necessary studies and tests, to determine the extent of graft compromise and its progression, if any; (3) education for physicians about diagnosing and treating any scarring that may result from using the device; and (4) medical treatment to remove the device from all *570 individuals exhibiting bypass graft compromise as a result of using the device.
Pursuant to Rule 12(b) of the Federal Rules of Civil Procedure, St. Jude moved for dismissal of Sutton’s complaint. St. Jude asserted Sutton lacks standing to pursue his action, and that he failed to state a claim upon which relief could be granted. Ruling that Sutton did not have standing, the district court dismissed his complaint for lack of subject matter jurisdiction. 2 Sutton timely appealed to this Court.
II. DISCUSSION
A. Jurisdiction and Standard of Review
This Court has appellate jurisdiction over the district court’s final judgment under 28 U.S.C. § 1291. We review an order dismissing a case for lack of subject matter jurisdiction
de novo. Joelson v. United States,
B. Standing under Article III
Sutton brings suit on behalf of a class of as-of-yet uninjured device implantees. In order to satisfy the standing-requirements of Article III of the Constitution, Sutton must meet three requirements. Failure to establish any one of them deprives a federal court of jurisdiction to hear the suit.
Lujan v. Defenders of Wildlife,
The Article III standing requirements apply equally to class actions. The class representative must allege an individual, personal injury in order to seek relief on behalf of himself or any other member of the class.
O’Shea v. Littleton,
C.Standing Based Upon Increased Risk of Future Harm
Sutton makes three main factual allegations in his complaint: (1) the device is defective and unreasonably dangerous; (2) implantation of the device puts Sutton and class members at a substantially greater risk for developing restenosis and occlusion of the bypass graft; and (3) this increased risk necessitates both current and future medical testing and monitoring.
*571
The district court found Sutton’s alleged injury “purely hypothetical” because he did “not provide[] the Court with any information from which to assess his allegedly increased risk of harm from implantation of the aortic connector.”
Sutton v. St. Jude Med., Inc.,
Sutton argues that exposure to an increased risk of disease has been recognized by federal courts as an injury in fact sufficient to confer Article III standing. He likens exposure to the device to exposure to toxins such as nuclear emissions and asbestos.
See Duke Power Co. v. Carolina Envtl. Study Group, Inc.,
In recent years, tort plaintiffs have increasingly sought, and have regularly been awarded, medical monitoring costs in both toxic tort and product liability cases.
See

et al, Medical Monitoring: A Viable Remedy for Deserving Plaintiffs or Tort Law’s Most Expensive Consolation Prize?,
27 Wm. Mitchell L.Rev. 521, 522 (2000) (citing
Day v. NLO,
The question of whether an increased risk of harm requiring current medical monitoring is a sufficient injury in fact to confer standing is one of first impression in this Circuit. The main basis found in the case law for allowing such claims to proceed is
Friends for All Children, Inc. v. Lockheed Aircraft Corp.,
A distinguishing feature of
Friends for All Children,
The Third Circuit considered medical monitoring in
In re Paoli Railroad Yard PCB Litigation,
While we consider the distinction set forth in
Paoli
helpful, we note that medical monitoring is more properly considered one of a number of possible remedies to an underlying tort, rather than a separately actionable tort.
See
Andrew R. Klein,
Rethinking Medical Monitoring,
64 Brook. L.Rev. 1, 10-11 (1998) (challenging the propriety of construing the cases as creating a unique cause of action and arguing in favor of the notion that medical monitoring “simply describes a potential remedy in established tort actions.”). Instead of “[t]he injury in an enhanced risk claim [being] the anticipated harm itself’ and “[t]he injury in a medical monitoring claim [being] the cost of the medical care that will, one hopes, detect that injury”,
Paoli,
In
Metro-North Commuter Railroad v. Buckley
considered a medical monitoring claim in the context of exposure to asbestos.
Two district courts in other Circuits have considered the issue of standing in increased risk of future harm cases, and have answered the inquiry in the affirmative.
See In re St. Jude Med., Inc.,
No. MDL 01-1396 JRT FLN,
In re Propulsid
found that a plaintiff who had previously used a heartburn drug causing irregular heartbeats in some users, but who had not herself developed any such injury, had alleged a sufficient injury in fact based on' the increased risk of harm. The court stated a broad standard for demonstrating injury in fact: “plaintiff has satisfied her burden of establishing this element [injury in fact] because the courts have long recognized that an
*574
increased risk of harm, which the plaintiff alleges, is an injury-in-fact.”
In re Propulsid,
In
Taylor v. Medtronics, Inc.,
Other courts have indicated they would not find standing to pursue medical monitoring costs in increased risk of future harm situations. One such case supporting the denial of standing to uninjured plaintiffs, relied upon by the district court in the instant case, is
Martin v. American Medical Systems, Inc.,
No. IP 94-2067-C-H/G,
Analyzing Sutton’s present action in light of the above precedent, we disagree with the result reached by the district court below. Sutton has alleged sufficient facts, when accepted as true, to suggest an increased risk of future harm resulting from being implanted with St. Jude’s device. Whether Sutton is likely to prevail on the merits is not a proper consideration at this time. We decline to preclude the *575 possibility of a plaintiff or class of plaintiffs bringing- suit under an increased risk of future harm theory due to the implantation of a medical device.
Though the plaintiffs in
In re St. Jude Medical, Inc.
were able to demonstrate a 700-percent increase in risk associated with using the heart valves there at issue, we hold it unnecessary for a plaintiff to make such a showing as a matter of course. Such a vast increase in the risk of injury clearly establishes an injury in fact, but to require a plaintiff to so clearly demonstrate her injury in order to confer standing is to prematurely evaluate the merits of her claims. Here Sutton alleges an increased risk of harm when comparing those individuals implanted with the device to those undergoing traditional surgery. Accepting Sutton’s allegations as true, the standing requirements have been met.
See Lujan,
The last two requirements for standing are easily met in this instance. The increased risk of future harm must be “fairly traceable” to St. Jude’s actions.
Friends of the Earth, Inc.,
The court below improperly concluded Sutton lacks standing to seek medical testing and monitoring allegedly made necessary by the implantation of a medical device that has not yet malfunctioned or caused Sutton any physical injuries, but presents an increased risk of future harm. We accordingly reverse and remand Sutton’s action.
III. TENNESSEE PRODUCT LIABILITY LAW
In the alternative, St. Jude moved for dismissal of Sutton’s complaint arguing that Tennessee product liability law does not allow a claim for medical monitoring where no physical injury or property damage manifests itself.

“As a general rule, appellate courts do not consider any issue not passed upon below.”
Dubuc v. Mich. Bd. of Law Exam’rs,
IV. CONCLUSION
For the foregoing reasons, we REVERSE the district court’s order of dismissal and REMAND the case for further evaluation consistent with this opinion.
Notes
. Sutton estimates the number of claimants to be approximately 50,000 people.
. The district court did not reach St. Jude’s failure to state a claim argument.
. A district court case from this Circuit has extensively discussed the issue of which states' laws allow for such actions.
See In re Telectronics Pacing Sys., Inc.,
.
Metro-North
also supports our framing of medical monitoring as a remedy rather than a separate tort.
. While we have included the particular factual findings of the district court in our discussion of the In re St. Jude decision, we again note that specific evidence of the alleged increased risk of harm is not a requirement to confer standing.
. Sutton also filed a Motion to Certify Questions of Law to Tennessee Supreme Court, which this panel has previously denied.
. In an effort to guide the district court on remand, we note that although Tennessee law is murky on the issue of whether claims for medical monitoring are cognizable, there are reasons why such claims are most probably proper. First, we note that two Tennessee cases at least suggest that the state recognizes medical monitoring claims.
