CROSS-REFERENCE TO RELATED APPLICATION This application is a continuation of U.S. patent application Ser. No. 17/690,274, filed Mar. 9, 2022, which is a continuation of U.S. patent application Ser. No. 16/240,203, filed Jan. 4, 2019, which claims priority to Korean Patent Applications No. 10-2018-0001851, filed on Jan. 5, 2018, and No. 10-2019-0000390, filed on Jan. 2, 2019, in the Korean Intellectual Property Office, and all the benefits accruing therefrom under 35 U.S.C. § 119, the contents of which are incorporated herein in their entirety by reference. BACKGROUND 1. Field The present disclosure relates to an organometallic compound, an organic light-emitting device including the same, and a diagnostic composition including the organometallic compound. 2. Description of the Related Art Organic light-emitting devices (OLEDs) are self-emission devices, which have improved characteristics in terms of a viewing angle, a response time, brightness, a driving voltage, and a response speed, and which produce full-color images. In an example, an organic light-emitting device includes an anode, a cathode, and an organic layer disposed between the anode and the cathode, wherein the organic layer includes an emission layer. A hole transport region may be disposed between the anode and the emission layer, and an electron transport region may be disposed between the emission layer and the cathode. Holes provided from the anode may move toward the emission layer through the hole transport region, and electrons provided from the cathode may move toward the emission layer through the electron transport region. The holes and the electrons recombine in the emission layer to produce excitons. These excitons transition from an excited state to a ground state, thereby generating light. Meanwhile, luminescent compounds, for example, phosphorescent compounds, may be used for monitoring, sensing, and detecting biological materials such as various cells and proteins. Various types of organic light emitting devices are known. However, there still remains a need in OLEDs having low driving voltage, high efficiency, high brightness, and long lifespan.
