Does Quest Diagnostics Report to Credit Bureaus
July 1, 2025

Quick Answer
Quest Diagnostics does not report patient billing information directly to credit bureaus. However, if a bill goes unpaid, it may be sent to a collections agency, which can then report the delinquent medical debt to the credit reporting agencies.
Quest Diagnostics and Your Credit
Quest Diagnostics is a major provider of clinical laboratory services in the United States. The company performs diagnostic testing for patients and physicians, analyzing samples like blood and urine to help diagnose and monitor diseases. It operates a large network of patient service centers and laboratories nationwide.
Quest Diagnostics does not offer credit products like loans or credit cards. However, an unpaid bill for their laboratory services can negatively impact your credit. If the debt becomes delinquent, it may be sold to a collection agency, which can then report the account to the credit bureaus.
Does Quest Diagnostics Report to Credit Bureaus?
Quest Diagnostics does not directly report your payment activity to major credit bureaus. However, if your account becomes significantly overdue, it may be transferred to a third-party collection agency. These agencies often report unpaid medical debts, which can then appear on your credit report. For specifics, contact Quest support.
Several factors can lead to a Quest Diagnostics bill ending up on your credit report:
- Significant Delinquency: Bills unpaid for an extended period, typically 90-180 days past the due date, risk being sent to collections.
- Ignoring Payment Notices: Failure to respond to multiple billing statements and final notices from Quest can trigger collections activity.
- Transfer to Collections: Once an account is sold or assigned to a collection agency, that agency may report the debt.
Who Does Quest Diagnostics Report Credit Information to?
While Quest Diagnostics does not report directly, the collection agencies they use will report delinquent accounts to the three major credit bureaus:
- Equifax
- Experian
- TransUnion
When does Quest Diagnostics Report to Credit Bureaus?
There isn't a specific, predetermined timeframe for when Quest Diagnostics reports to credit bureaus. The process is not automatic and depends on several individual factors. Typically, an unpaid bill must first become significantly delinquent. After multiple attempts to collect the payment fail, Quest may turn the account over to a third-party collection agency. It is this agency, not Quest Diagnostics directly, that will then report the unpaid debt to the major credit bureaus. The exact timing for when an account goes to collections and is subsequently reported can vary widely based on the age of the debt, the amount owed, and the policies of the specific collection agency involved.
How Reporting Can Affect Your Credit Score
Positive impact
- Paying off a Quest collection can boost your score, as newer FICO and VantageScore models may ignore paid medical collection accounts completely.
- Successfully disputing and removing an incorrect Quest collection from your report will immediately delete the negative mark, which can significantly raise your score.
Potential negatives
- An unpaid bill sent to collections adds a derogatory mark to your report, which can severely damage your payment history and lower your score.
- The collection account stays on your report for up to seven years, negatively impacting your ability to get approved for new credit or loans.
Tips for Managing Credit with Quest Diagnostics
- Review every bill for accuracy. Compare the services listed with the tests you received to identify and dispute any errors before they affect your credit.
- Understand your insurance benefits before testing. Knowing what your plan covers helps you anticipate out-of-pocket costs and budget accordingly to prevent unexpected debt.
- Proactively contact Quest’s billing department if you cannot pay in full. They often provide payment plans or financial assistance options to help you avoid delinquency.
- Keep meticulous records of all bills, payments, and correspondence. This documentation is crucial for efficiently resolving any disputes with Quest or your insurance company.
Frequently Asked Questions
What happens if I don’t pay my Quest Diagnostics bill?
If your bill remains unpaid, Quest will likely sell the debt to a third-party collection agency. This agency will then attempt to collect the payment from you and will probably report the delinquent account to the major credit bureaus, negatively impacting your credit score.
How can I remove a Quest collection from my credit report?
To remove a collection account, you can dispute any inaccuracies with the credit bureaus directly. Alternatively, you can negotiate a "pay-for-delete" agreement with the collection agency, where they agree to remove the entry from your report in exchange for your payment of the debt.
Will paying a collection account improve my credit score?
Paying off a collection is beneficial, but it doesn't automatically erase the negative mark. Newer scoring models like FICO 9 and VantageScore 3.0 ignore paid collections, so your score may improve. However, older models still used by many lenders will factor it in.
