Impact of Blood Sample Collection and Processing Methods on Glucose Levels in Community Outreach Studies

Table 1

Mean glucose and HOMA values as well as rates of IFG and MetS_IFG and MetS_HOMA for NaF-treated tube and centrifuged plain Tube.

	Centrifuged Plain Tube	NaF Tube	𝑃 value
Fasting glucose (mmol/L) ± SD	84.56 ± 6.42	81.02 ± 5.82	<0.01
HOMA-IR	2.29 ± 1.82	2.1 ± 1.78	<0.01
IFG (≥100 mmol/L) % (𝑛)	1.56 (4)	0.39 (1)	0.083
HOMA-IR ≥3.99% (𝑛)	9.38 (24)	8.59 (22)	0.158

HOMA-IR: Homeostatic model assessment of insulin resistance; IFG: impaired fasting glucose.
