LOINC Code 62679-6: PhenX - contact biometry protocol 110101
62679-6 is a LOINC code used to identify PhenX - contact biometry protocol 110101 in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component PhenX - contact biometry protocol 110101. It is commonly used with the system or sample type ^Patient.
What is this code?
LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component PhenX - contact biometry protocol 110101. It is commonly used with the system or sample type ^Patient.
When is it used?
- Used in lab systems, EHRs, and clinical data exchange.
- May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
- Status: ACTIVE
- Panel type: Panel
- Method: PhenX
What it does not mean
- The code identifies the observation or test, not the actual result.
Key facts
- PhenX - contact biometry protocol 110101
- The axial length of the eye and central corneal thickness is measured in this protocol using the Ultrasonic A scan/pachymeter DGH 4000B SBH IOL Computation module. (A-Scan pachymeter, Ultrasonic, Exton, PA) which requires direct contact with the cornea. Three measurements are taken on each eye for both axial length and central corneal thickness. Results of all measurements are then printed. The WG recommends that three readings be taken and recorded from each eye for both axial length and central corneal thickness (measurements in millimeters). The WG recommends that the central corneal thickness-pachymetry measurements be taken first followed by the axial length measurements, as presented in this protocol. This protocol for contact biometry uses the ultrasonic A scan/pachymeter DGH 4000B SBH IOL Computation module. Other instruments can be used to measure ocular biometry including axial length and central corneal thickness. If other instruments are used, the reproducibility of the measurements should be comparable to those acquired with this protocol. In addition, when other instruments are used to collect these measurements, the manufacturer and model of equipment should be recorded. These other devices may require some different steps than are described in this protocol. Investigators should follow the equipment manufacturer's instructions to ensure quality control.
