Participants’ (n = 112) A1C values were measured using both the A1CNow and DCA devices by trained research staff at the church locations. Of the 112 participants, 74 were returning participants (participated in Phase 1 data collection), and 38 were newly recruited. A1CNow tests were performed twice to be consistent with the Phase 1 data collection protocol. However, the two tests were performed simultaneously using two A1CNow devices to reduce participant burden (e.g., multiple finger pricks, longer wait time) and to accommodate high-volume community-based testing. The DCA test was performed once as a reference measurement and an A1C value and fasting blood glucose concentration (Cholestech LDX, Alere) were recorded.
Cholestech ldx
Manufactured by Abbott
Sourced in United States
The Cholestech LDX is a compact, desktop laboratory instrument designed to perform cholesterol and other lipid panel tests. It uses a small sample of blood to provide quick and accurate measurements of total cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides.

Total cholesterol and fasting plasma glucose (FPG) were both measured with a commercially available analyzer (Cholestech LDX, Alere, Waltham, MA). Forty microliters of blood were collected via finger stick and injected into a Cholestech LDX lipid profile with glucose cassette. The normative value for total cholesterol is below 200 mg/dL, while the normative value for FPG is below 100 mg/DL.

Participants arrived at the laboratory between 07.00 and 09.00 in a fasted, euhydrated state after avoiding alcohol and exercise for a 24 h period. Following an initial briefing, resting heart rate (RHR), systolic and diastolic blood pressure (SBP and DBP, respectively) were measured using a manual sphygmomanometer (Accoson Greenlight 300, Accoson, United Kingdom). Stature (to the nearest 0.1 cm) and body mass (to the nearest 0.1 kg) were recorded using a stadiometer (Seca 220, Hamburg, Germany) and calibrated electronic scales (Seca 220, Hamburg, Germany). Body mass index (BMI) was derived by calculating mass/height2. Finger capillary blood samples were obtained and analysed for total cholesterol, high-density lipoprotein, low-density lipoprotein, triglycerides and glucose using a Cholestech LDX (Alere San Diego, Inc., San Diego, CA) capillary whole blood lipid analyser (Donato et al. 2015 (link)).

The research participants were told to keep the empty stomach for more than total 12 hr by fasting from 7 p.m. on the night before the test, and the test was performed in the next morning. In the blood lipids test, the blood sample that was taken in the finger tip method was measured through the equipment called Cholestech LDX (Alere, Oslo, Norway). After taking the blood sample (about 35 μL) from the index fingertips of research participants, the kit containing the blood sample was inserted in the measurement equipment for analysis. Following the manufacturer’s protocol, the figures of triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), LDL-C, and TC were automatically calculated 5 min later (Marcus et al., 1992 (link)).

Blood cholesterol, triglycerides and fasting plasma glucose will be assessed from an overnight fasted (minimum eight-hours) fingertip blood sample. Samples will be collected by research personnel experienced in fingertip blood sampling techniques and analysed on-site using Cholestech LDX (Alere Inc., Waltham, MA) technology. The Cholestech LDX analyser shows excellent agreement with laboratory analyses
[46 (link)] and has been validated as an alternative to laboratory analyses for assessing the presence of metabolic syndrome
[47 (link)].

During normal working hours, individuals attended the occupational health department for an appointment lasting 60 min. During the visit, demographic (date of birth, gender, postcode of residence) and anthropometric (body mass, height, waist circumference) data were collected. Systolic and diastolic blood pressure, heart rate and rhythm (to screen for cardiac arrhythmias), smoking status, dietary habits (fruit and vegetable consumption), family and medical histories were recorded and blood samples obtained. Blood samples were collected via capillary puncture and analysed for total, high-density lipoprotein (HDL) and low-density lipoprotein (LDL) cholesterol; triglycerides; blood glucose (Cholestech LDX; Alere Inc., Orlando, FL, USA); and HbA 1c (DCA 2000; Siemens Healthcare Diagnostics Ltd, Frimley, UK). In addition, current physical activity levels were assessed by the General Practice Physical Activity Questionnaire (GPPAQ). 14
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
