What Do Lab Test Results Indicate?

Question : Can you please advise whether i am pre-diabetic; and, if so, what can i do to not become a diabetic type 2?

My test results are:

6 Mar. 2012: SERUM/PLASMA GLUCOSE fasting, serum 5.8* mmol/L (3.4 to 5.4): 'A fasting glucose level of 5.5 to 6.0 mmol/L is in a zone of uncertainty. This patient's result is therefore equivocal. Suggest follow-up as clinically indicated.'

12 Mar. 2012: 2 HR GLUCOSE TOLERANCE TEST: fasting 5.5 mmol/L (reference ranges 3.4 to 5.4; diabetic ranges >6.9); 1: 11.7* mmol/L; 2: 6.3 mmol/L(reference ranges 11.0): 'Fasting glucose in the range 5.5 to 6.0 mmol/L and 2 hour glucose <7.8 mmol/L. The fasting glucose result is indeterminate but less than that required to diagnose impaired fasting glycaemia. Suggest follow up review as clinically indicated'

25 Aug. 2012: GLYCATED HAEMOGLOBIN (HBA1c): HbA1c-NGSP (4.0-6.0%): 6.0%; HbA1c-IFCC (20-42 mmol/mol): 42 mmol/mol;
8 Sep. 2012: GLYCATED HAEMOGLOBIN (HBA1c):HbA1c-NGSP (4.0-6.0%): 5.7%; HbA1c-IFCC (20-42 mmol/mol): 39 mmol/mol;
7 Dec. 2012: GLYCATED HAEMOGLOBIN (HBA1c): HbA1c-NGSP (4.0-6.0%): 6.2%; HbA1c-IFCC (20-42 mmol/mol): 44 mmol/mol
6 Aug 2013: GLYCATED HAEMOGLOBIN (HBA1c): HbA1c-NGSP (4.0-6.0%): 5.5%%; HbA1c-IFCC (20-42 mmol/mol): 36 mmol/mol
'The most commonly recommended target for glycated haemoglobin in ordinary diabetic adult patients is an HbA1c of < 6.5 to 7.0% (48 to 53 mmol/mol). For some patients a tighter glycaemic target of <6.0% (42 mmol/mol) may be appropriate, if it is clinically attainable. For patients with severe and/or frequent hypoglycaemia, less intensive targets may be appropriate.'

7 Dec. 2012: SERUM/PLASMA GLUCOSE:random, serum (3.4 to 7.7 mmol/L):6.1.
