Biometric Tests

A biometric screening sometimes called a biometric health screening or biometric assessment provides a clinical assessment of key health measures. These results may be used to identify certain health conditions, such as diabetes and heart disease, or to indicate an increased risk for these conditions.

A biometric screening is an important part of a health and wellness program. A screening may be conducted at an employee health fair, at a commercial laboratory, at a provider’s office, or at home using a kit. Most employers offer a variety of options to allow all employees, and sometimes spouses, to participate in the screening program.

What’s included in a biometric screening?

During a biometric screening, clinicians:

  • Draw blood (often using a finger prick) to measure cholesterol, glucose, and triglycerides
  • Capture resting blood pressure rate
  • Record height, weight, waist circumference, and BMI measurements

These same measurements can be captured through a screening at a medical center, a worksite, or at a commercial lab. The results from the blood draw may take up to 10 days, depending upon the method. Most clinicians prefer to use a fingerstick to provide immediate results.

Comprehensive Trail-Making Test (CTMT)

The Comprehensive Trail-Making Test (CTMT) is an assessment based on time-tested techniques. The CTMT is a standardized set of five visual search and sequencing tasks that are heavily influenced by attention, concentration, resistance to distraction, and cognitive flexibility (or set-shifting). Its primary uses include the evaluation and diagnosis of brain injury and other forms of central nervous system compromise. More specific purposes include the detection of frontal lobe deficits; problems with psychomotor speed, visual search and sequencing, and attention; and impairments in set-shifting.

Neuropsychological testing is necessary for a variety of contexts and performed by a variety of professionals. Neuropsychologists; clinical, counseling, school, and pediatric psychologists; occupational therapists; speech and language professionals; physical therapists; and others interested in objective testing of functionality in brain-behavior relationships would all benefit from using the CTMT.

The CTMT is for individuals ranging in age from 8 years through 74 years. The administration is timed and takes approximately 5 to 12 minutes. Scoring typically requires less than 5 minutes. Normative scores are provided in the form of T-scores, having a mean of 50 and a standard deviation of 10, along with their accompanying percentile ranks.

The basic task of trail-making is to connect a series of stimuli (numbers, expressed as numerals or in word form, and letters) in a specified order as fast as possible. The score derived for each trail is the number of seconds required to complete the task. The composite score is obtained by pooling the T-scores from the individual trails. The five trails are similar but also are different in some significant way. This easily administered set of tasks is remarkably sensitive to neuropsychological deficits of many types.
