On May 17 and 18, a business called Life Line Screening will visit the Bangor area.

The firm offers a package of five screenings it says can help consumers avoid cardiovascular disease. The screenings are intended to detect plaque buildup in carotid arteries, abdominal aortic aneurysms and other signs of cardiovascular irregularities.

Life Line Screening offers the five screenings for $149, cash or credit cards accepted. The business does not accept Medicare and does not do private insurance billings.

The brochure advertising the screenings recently in the Bangor Daily News had this statement regarding cancellations: “A full refund is issued if you call to cancel at least 2 days prior to your appointment. If less than 2 days’ notice is given, we will issue a Gift Card for the full amount to be used by you, or anyone you choose, to purchase future screening services.”

The Maine Medical Association has taken a close look at the screenings offered by Life Line Screening during prior visits. Maine Medical Association Executive Vice President Gordon Smith told me that the company does business in conjunction with a physician who is licensed in Maine (although that doctor need not live here).

Smith also said he knows of no problem with the technology of the screenings. He said the tests may offer some consumers peace of mind, should their results come back negative.

Life Line Screening says it will report results within 21 days; it urges those who’ve been screened to take the results to their family doctors for any follow-up tests or other procedures.

Smith and others in the medical community contend that consultation with the family physician should take place before the screening, to make sure the tests are really needed.

Smith said physicians are concerned about “mass testing,” screenings that are offered without regard to people’s medical histories or individual situations. Smith said he worried about “tests that end up with more false positives than real positives, and patients receiving treatment that’s at best unnecessary and at worst harmful.”

Screenings can show irregularities that may or may not be harmful to someone’s health.

Follow-up testing — especially among older patients — can create different levels of risk depending on the patient’s status; the worry and uncertainty that go along with further testing take a toll as well.

Smith told me that Life Line Screening does not accept Medicare because Medicare doesn’t pay for the screenings the firm offers. Smith said Medicare’s reasoning appears to be that the screenings “haven’t been identified as being valuable screening tests for patients, generally.” Testing an individual based on a physician’s advice is one thing; Smith said random testing usually accomplishes very little.

Many consumer advocates sound off about individual choice, and informed choice is great. Smith advises people who don’t have a family physician to do their own research online (researchers at your local library can help).

In the 2007 book “Overtreated,” Shannon Brownlee contended that a lot of medical care is unnecessary and therefore wastes resources better spent on those who need care. Our advice is to be proactive but, in making any serious health decision, consult your physician first.
