New from Loop · The Retest Guarantee

The health checkupthat checks back

When an employee's blood test comes back in the critical range, Loop doesn't stop at the report — we call within 24 hours, guide a 3-month recovery plan, and then retest them for free to prove it worked.

The gap nobody closes
9 in 10 employees value their health check.
8 in 10 never act on it.

Every provider sells an annual checkup. The lab report lands, and for most employees the journey ends right there — including those who need more care. The report was not meant to be the outcome.

What counts as critical?

Only critical results trigger the retest — and we're precise about it.

Every parameter is graded on a published three-band scale. A result that drifts out of range gets guidance. A result in the critical band gets the full loop: outreach, consult, plan, and the free retest.

In rangeAll clear
The result sits in the healthy band. No action needed — a green marker on the report.
Out of rangeWatch
Drifting from healthy. Flagged on the report with guidance to monitor and improve.
CriticalAct now
Clinically concerning. This is the trigger — outreach within 24 hours, and the Retest Guarantee applies.

Triggers the guarantee

An employee at HbA1c >8.0% gets a call within 24 hours, a doctor consult, a 3-month plan — and a free diabetic-profile retest to confirm the number came down.

For HR & benefits leaders

One programme. Four wins for your team.

You already pay for the health check. The Retest Guarantee makes sure that spend is worth it — in utilisation, in fewer claims, and in how your people talk about their benefits.

  • Higher utilisation
    A visible road to recovery gives employees a reason to actually use the benefit — not just book it and forget it.
  • Prevention over claims
    No flagged employee slips through the cracks. Care today instead of a high-cost hospitalisation claim tomorrow.
  • Zero added budget
    Consults, follow-ups and free retests are carved out of the checkup spend you've already committed. No new line item.
  • Be first to it
    No other corporate health plan closes this loop. Bring your people a benefit nobody else offers — and be the HR that did it first.

The guarantee rides on a checkup that already works.

FAQ

Questions, answered.

Any covered employee whose checkup returns a result in the critical band — not merely out of range. The bands are published per parameter, so there's never ambiguity about who's in.

After the guided action plan — typically three months from the original test, which is the clinically meaningful window for most parameters to respond to treatment and lifestyle change. The employee gets a reminder when it's time; nothing to track manually.

The full relevant clinical profile, not just the single flagged parameter. A critical LDL unlocks a complete lipid profile retest; a critical TSH unlocks the full thyroid profile — so the doctor sees the whole picture both times.

Nothing beyond your existing checkup programme. Outreach, doctor consults, action plans and the retests themselves are included — carved out of spend you've already committed, not added to it.

Never. Employees own their reports. HR gets aggregate utilisation and workforce health trends through the quarterly Health Index — visibility without ever touching an individual's medical data.

Everyone offers the health check.
We offer what comes after.
