OPINION
Plaintiffs-appellees are seven former employees of Dura Automotive Systems who are challenging Dura’s drug testing *284 policy under the Americans with Disabilities Act. In resolving the parties’ cross motions for summary judgment, the district court held that an individual need not be disabled to pursue a claim under section 12112(b)(6) of the Act. The district court certified this issue for interlocutory appeal, which a panel of this Court granted. We now REVERSE the district court’s decision and hold that an individual must be disabled to pursue a claim under 42 U.S.C. § 12112(b)(6).
I.
As this interlocutory appeal presents a purely legal issue, we will only briefly summarize the relevant facts to provide context. The Employees are seven individuals who worked at Dura’s Lawr'enceburg, Tennessee manufacturing facility. Dura manufactures glass window units for cars, trucks, and busses, and the Employees performed a wide range of jobs at Dura including driving tow motors, assembling windows, painting primer on frames, and trimming and water testing windows.
Dura grew concerned that the Lawrenceburg facility had a higher rate of workplace accidents than comparable plants and suspected that this might be caused by either legal or illegal drug use. To improve safety, Dura implemented a policy that prohibited employees from using legal prescription drugs if such use adversely affected safety, company property or job performance. Dura worked with an independent drug testing company to set up a procedure to screen its employees for substances it believed could be dangerous in the workplace. The resulting policy screened employees for twelve substances including those commonly found in legal prescription drugs such as Xanax, Lortab, and Oxycodone.
Each of the Employees tested positive for one of the twelve prohibited substances. In each case, the individual had a legal prescription for a drug containing that substance. Dura gave each of the Employees an opportunity to transition to drugs without the prohibited substances, but refused to consider letters from doctors stating that the Employees’ work performance would not be affected by the drugs. Eventually, Dura terminated the Employees when they continued taking medication with the prohibited substances.
The Employees sued, claiming that Dura’s drug testing violates the Americans with Disabilities Act. In resolving the parties’ cross motions for summary judgment, the district court concluded that six of the Employees are not disabled as a matter of law. 1 The district court held that the Employees’ claim that Dura’s actions constituted an impermissible medical examination is best analyzed under section 12112(b)(6). The district court denied the Employees’ summary judgment motion, finding that there was a disputed issue of material fact as to whether Dura’s justification for the drug testing falls within the exception in the Act for testing that is job related and consistent with business necessity.
Dura then moved for clarification, asking the district court to determine whether individuals must be disabled in order to pursue claims under section 12112(b)(6). The district court affirmed its initial decision that individuals do not need to be disabled to assert claims under section *285 12112(b)(6), but, recognizing that there is a difference of opinion on this question, certified this issue for interlocutory appeal. A panel of this Court granted the petition for leave to appeal on the issue of whether an individual must be disabled to pursue a claim under section 12112(b)(6) of the Act.

A. Standard of Review
Because this is an interlocutory appeal, we cannot review the district court’s findings of fact and must consider only pure questions of law.
Nw. Ohio Adm’rs, Inc. v. Watcher & Fox, Inc.,
B. The Text of Section 12112
Section 12112 of the Act prohibits discrimination against a “qualified individual with a disability because of the disability.” 42 U.S.C. § 12112(a) (2006). 2 In pertinent part, this section provides:
(a) General Rule
No covered entity shall discriminate against a qualified individual with a disability because of the disability of such individual ...
(b) Construction
As used in subsection (a) of this section, the term “discriminate” includes
(6) using qualification standards, employment tests or other selection criteria that screen out or tend to screen out an individual with a disability or a class of individuals with disabilities unless the standard, test or other selection criteria, as used by the covered entity, is shown to be job-related for the position in question and is consistent with business necessity....
Id. § 12112.
Although non-disabled individuals may bring claims under some provisions of the Act, the plain text of subsection (b)(6) only covers individuals with disabilities. The text of subsection (a) and (b)(6) specifically refers to “qualified individuaos] with disabilities],” and not, as discussed below, a broader class of individuals such as “employees.”
See id.
§ 12112(a), (b)(6). We endeavor to “read statutes and regulations with an eye to their straightforward and commonsense meanings.”
Henry Ford Health Sys. v. Shalala,
Although the Employees argue that subsection (b)(6) should be read in conjunction with subsection (d)(4), we do not believe that is necessary in light of the clarity of subsection (b)(6). As the Supreme Court has noted, “when a statute
*286
speaks with clarity to an issue judicial inquiry into the statute’s meaning, in all but the most extraordinary circumstance, is finished.”
Estate of Cowart v. Nicklos Drilling Co.,
Additionally, requiring that an individual be disabled to pursue claims under section 12112(b)(6) gives effect to Congress’s choice of language. When Congress uses different language in different parts of the same act, we endeavor to give effect to that different language.
See Rodriguez v. United States,
III.
The district court also held that the Employees had not asserted claims cognizable under section 12112(d)(4) of the Act, challenging Dura’s drug testing policy as an improper “medical examination or inquiry.” The Employees challenge this ruling in their appellate brief. This ruling, however, was not certified for interlocutory appeal.
The doctrine of pendent appellate jurisdiction allows an appellate court, in its discretion, to exercise jurisdiction over is
*287
sues that are not independently appeal-able, but are “inextricably intertwined” with matters over which the appellate court properly and independently has jurisdiction.
Chambers v. Ohio Dep’t of Human Servs.,
145 F.Sd 793, 797 (6th Cir.1998). However, the “inextricably intertwined” requirement is not meant to be loosely applied as a matter of discretion.
Id.
Rather, the “inextricably intertwined” requirement is satisfied only if the resolution of the properly appealable issue “necessarily and unavoidably” decides the nonappealable issue.
Wedgewood Ltd. P’ship I v. Twp. of Liberty,
As the Employees have not demonstrated that the district court’s ruling on them putative claims under section 12112(d)(4) is inextricably intertwined with the certified issue, we decline to exercise pendent appellate jurisdiction and express no opinion as to that part of the district court’s decision.
IV.
For the reasons set forth above, we REVERSE the district court’s decision that non-disabled individuals can pursue claims under section 12112(b)(6) of the Act. On remand, the district court shall dismiss the claims of the non-disabled Plaintiffs under section 12112(b)(6) of the Act.
Notes
. The district court held that there is a question of fact as to whether one of the Employees, Willarene Fisher, qualifies as disabled because of a "record of disability." However, because this appeal only involves issues relating to a non-disabled individual’s ability to challenge Dura's policy, this opinion assumes that none of the Employees are disabled, and does not separately analyze Fisher's claims.
. The 2008 amendments to the Act are inapplicable to this case as we have held that they do not apply retroactively.
Milholland v. Sumner Cnty. Bd. of Educ.,
. In pertinent part, subsection (d)(4) provides:
A covered entity shall not require a medical examination and shall not make inquiries of an employee as to whether such employee is an individual with a disability or as to the nature or severity of the disability, unless such examination or inquiry is shown to be job-related and consistent with business necessity.
42 U.S.C. § 12112(d)(4)(A) (emphasis added).
