Exhibit 3.56

THE LMC REVOCABLE TRUST

Revocable Trust Agreement

NRS 89.070(1)

This trust agreement is made on November 30, 2007, between Aurora LMC, LLC, a Nevada limited liability company (“trustor”), and James C. New, of 11360 N. Jog Road, Palm Beach Gardens, Palm Beach County, Florida; Martin J. Stefanelli, of 11360 N. Jog Road, Palm Beach Gardens, Palm Beach County, Florida; and Marcus Erling, M.D., of 3059 South Maryland Parkway, Suite 100, Las Vegas, Clark County, Nevada (“trustees”) for the purpose of enabling the trustees to hold and manage the trust estate and to carry on business as provided below.

The revocable trust created in this instrument may be referred to as “THE LMC REVOCABLE TRUST” (this “Trust”). Trustor intends that this Trust be treated as a “grantor trust” under Internal Revenue Code Sections 671, 675, 676 and 677 during the trustor’s existence, so that solely for federal income tax purposes, the trustor is deemed the owner of the entire trust corpus and income. Trustees declare that all property now held or acquired after the effective date of this declaration by them or either of them or their successors, as trustees, and all income and profits from such property, shall be by them managed, administered, received, collected, disposed of, and distributed for the benefit of Aurora LMC, LLC as the designated beneficiary (“beneficiary”) of this instrument and any amendments to this instrument.

SECTION ONE

TRUST ESTATE

Trustor assigns, transfers, and conveys to trustees the property described in the attached Exhibit A, which is incorporated by reference, and the receipt of which property is acknowledged by trustees. The property shall be held by trustees in trust for the purpose described below.

SECTION TWO

PURPOSE

Trust is authorized to purchase or otherwise acquire the whole or any part of the business, property, or other assets of any person or company carrying on any business that any individual trustee of this Trust is authorized and empowered to conduct, including professional corporations incorporated to perform professional medical services. Specifically, Trust is authorized to purchase 100% of the capital stock of Laboratory Medicine Consultants, Ltd., a professional corporation. It is intended that the acquisition of 100% of the capital stock of Laboratory Medicine Consultants, Ltd. be in compliance with NRS 89.070(1).

SECTION THREE

REVOCATION AND AMENDMENT

Trustor reserves the right at any time, by an instrument in writing delivered to trustees, to revoke or amend this Trust in whole or in part. The duties and liabilities of trustees shall under no circumstances be substantially increased by any amendment of this agreement except with their written consent.

Marcus Erling, M.D., or a successor trustee licensed as a physician under Chapter 630 of the Nevada Revised Statutes (or the equivalent successor thereto) (the “Physician Trustee”), shall have the power to revoke this trust in the event of a violation of either of (i) Nevada health care laws, including but not limited to the corporate practice of medicine doctrine, or (ii) the professional medical ethical guidelines.

Upon revocation, all property of the trust, including the shares of stock of any business acquired by the trust, shall revert and be transferred to trustor. Notwithstanding the foregoing, if upon revocation, the trust property includes stock of Laboratory Medicine Consultants, Ltd., a professional corporation, such stock shall either (i) be sold to a third party in a manner compliant with Chapter 89 of the Nevada Revised Statutes and the proceeds of such sale shall be transferred to trustor or (ii) be transferred to a third party appointed by trustor in such a manner as to be compliant with NRS 89.070(1).

SECTION FOUR

DISPOSITION OF INCOME AND PRINCIPAL AND OTHER TRANSACTIONS
WITH TRUSTOR

After paying the necessary expenses incurred in the management of the trust estate, if any, trustees shall pay the net income of the Trust and distribute the principal of the Trust in the following manner:

Trustees shall pay the beneficiary the net income of the trust estate, in convenient installments or as the beneficiary may direct from time to time, and shall distribute to the beneficiary such part, or all, of the principal of the trust estate as the beneficiary may request in writing from time to time. Additionally, the trustees, in the trustees’ discretion, may at any time distribute to the beneficiary such portion or portions of the principal of the trust estate as the trustees may deem necessary or advisable.

Upon dissolution, all property of the trust, including the shares of stock of any business acquired by the trust, shall revert and be transferred to trustor. Notwithstanding the foregoing, if upon revocation, the trust property includes stock of Laboratory Medicine Consultants, Ltd., a professional corporation, such stock shall either (i) be sold to a third party in a manner compliant with Chapter 89 of the Nevada Revised Statutes and the proceeds of such sale shall be transferred to trustor or (ii) be transferred to a third party appointed by trustor in such a manner as to be compliant with NRS 89.070(1).

Trustor shall have the right, at any time exercisable in a non-fiduciary capacity, without the approval or consent of any person acting in a fiduciary capacity, to acquire any property then held in the trust by substituting other property of an equivalent value.

Trustor shall have the right to borrow some or all of the Trust principal without providing any security for repaying the loan.
