•    Potential Biomarker: Serum levels of lipid hydroperoxide (LOOH)
•    Type:    Serum
•    Relevance: The serum levels of lipid hydroperoxide have been considered as a potential biomarker for anxiety disorders among children (Ceylan et al., 2014).

•    Potential Biomarker: Nighttime Fears (NF)
•    Type: Behavioral
•    Relevance: Nighttime Fears (NF) may be a potential behavioral biomarker for anxiety vulnerability, fears, and behavioral problems among children, especially those preschool children of 4 -6 years old (Kushnir et al., 2014).

•    Potential Biomarker: BAIAP3 SNPs (AA for rs2235632, TT for rs1132358)
•    Type:    Genetic variants
•    Relevance: The genetic polymorphisms of BAIAP3 (BAI1 Associated Protein 3) may be the potential biomarkers for anxiety among women and benzodiazepine abuse    among men (Wojcik et al., 2013).

•    Potential Biomarker: Cone of Direct Gaze: CoDG (“range of eye gaze angles judged as being directed at oneself”)
•    Type: Psychophysical
•    Relevance: CoDG has been suggested as a potential psychophysical biomarker for social anxiety disorder (Jun et al., 2013).

•    Potential Biomarkers: Abnormal cerebrospinal fluid (CSF) Aβ42 and t-tau levels
•    Type: Cerebrospinal fluid (CSF)
•    Relevance: Abnormal levels of cerebrospinal fluid (CSF) Aβ42 and t-tau can be the potential biomarkers for the symptoms of anxiety, agitation and irritability among those with mild cognitive impairment (MCI) (Ramakers et al., 2013).

•    Potential Biomarker: Electroencephalographic activities (P1 activation, N2 activation)
•    Type: Neurophysiological
•    Relevance: The Electroencephalographic activities may be the potential biomarkers for the outcomes of cognitive behavioral therapy (P1) and responses (N2) among anxious children (Hum et al., 2013).

•    Potential Biomarkers: Higher HDL, free fatty acids (FFA), dehydroepiandrosterone-sulfate (DHEA-S), substance P
•    Type: Plasma biochemical markers
•    Relevance: Higher levels of HDL, FFA, DHEA-S, and substance P may indicate anxiety and degraded mood among females (Lieberman et al., 2012).

•    Potential Biomarkers: Elevated dark-enhanced startle, sympathetic system activation
•    Type: Psychopathological markers
•    Relevance: Elevated dark-enhanced startle and sympathetic system activation may be a marker for anxiety among children with abused mothers (Jovanovic et al., 2011).

•    Potential Biomarker: Higher cortisol levels in saliva
•    Type: Saliva biochemical markers
•    Relevance: Higher cortisol levels in saliva may be a potential marker for psychosomatic halitosis (PH) (oral malodor) with anxiety (Fukui et al., 2010).

•    Potential Biomarker: Aversive learning, aversive conditioning
•    Type:    Behavioral
•    Relevance: Aversive learning may be a potential biomarker for anxiety disorders among children (Craske et al., 2008).

•    Potential Biomarker: CO2 sensitivity
•    Type: Psychophysical
•    Relevance: The CO2 sensitivity may be a potential biomarker for social anxiety disorder (SAD) among young adults (Schmidt et al., 2008).

•    Potential Biomarkers: Inflammation and coagulation markers in men: C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), homocysteine, fibrinogen levels; in women: CRP, white blood cell counts, IL-6, homocysteine, fibrinogen levels
•    Type: Inflammation and coagulation markers
•    Relevance: Inflammatory and coagulation markers including CRP and IL-6 may be associated with anxiety among men (19-89 years old) and women (18 to 84 years old) (Pitsavos et al., 2006).

•    Potential Biomarker: Glyoxalase-I protein
•    Type: Protein marker in the brain areas
•    Relevance: The glyoxalase-I protein may be a potential biomarker for anxiety- and depression-like behavior, as identified in mice models (Krömer et al., 2005).

•    Potential Biomarker: Anxiety sensitivity (phrenophobia, fear of physical arousal)
•    Type: Psychological
•    Relevance: Phrenophobia may be a potential biomarker for anxious symptoms among young psychiatric inpatients between 9-17 years old (Joiner et al., 2002).

•    Potential Biomarker: Cholesterol levels
•    Type: Biochemical marker
•    Relevance: Cholesterol levels have been associated with anxiety and depression among a normal population in a primary care setting (Rafter et al., 2001).

•    Potential Biomarkers: Higher levels of CD16 (natural killer) cells; CD19 cells (B lymphocytes), human leukocyte antigen (HLA)-DR-presenting cells, HLA-DR and CD19 surface markers (B lymphocytes with surface HLA-DR)
•    Type: Circulating lymphocyte phenotypic markers
•    Relevance: Higher levels of natural killer cells, B lymphocytes, and HLA-DR-presenting cells have been associated with anxiety disorders, panic disorder, and generalized social phobia (Rapaport et al., 1998).

•    Potential Biomarker: Plasma levels of glucose, cortisol and prolactin
•    Type: Plasma biochemical markers
•    Relevance: The plasma levels of glucose, cortisol and prolactin may be related to anxiety caused by physiology examination (EPh) and psychology (EPs) examination among female medical students (Armario et al., 1996).

•    Potential Biomarker: Frontal midline theta activity
•    Type:    Physiological
•    Relevance: Frontal midline theta activity has been considered as a potential biomarker for anxiety among male university students (Mizuki et al., 1989).
