Please help me interpret this ultrasound!

Results are
"The Thyroid gland is enlarged with the right lobe measuring 4.8 cm in length, the left thyroid lobe measuring 4.6 cm in length, and the isthmus measuring 6mm in thickness.  The thyroid parenchyma is diffusely heterogeneous.  Within the thyroid parenchyma, a discrete nodule or cyst is not detected.  Immediately inferior to the lower pole of the left thyroid lobe. There is a 15mm circumscribed nodule which appears to exhibit a plane of seperation from the lower pole of the left thyroid lobe.  This may reflect a midly enlarged lymph node.

IMPRESSION
1. Thyroid enlargement with heterogeneous parenchyma.
2. No definite intrinsic nodule or cyst within the thyroid gland.
3. 15 mm solid nodule inferior to the lower pole of the left thyroid lobe with an apparent plane of separation from the lower pole of the left thyroid lobe.  This may reflect an enlarged lymph node.  This could be further characterized with CT scanning if clinically indicated.



Also, on my blood test MCH was high as normal range is 27-31 [mine is 32].   MPV is low at 7 where normal range is 7.5-10.5.  

AND Squamous Epithelial Cells are high measuring at 10-20 while normal range is 0-5.
What does this mean?
Please someone help interpret this or even just offer an opinion.... anything is GREATLY appreciated!!
