Need help understanding bloodwork?

There are a few values in red. I understand my potassium is low, but I don't know what the GFR is. I've been having palpitations. Possibly related to anxiety. The cardiac workup at the ER came back clear. Just need help understanding the values in red.

GFR (glomerular filtration rate), which measures the filtration of blood in the kidneys. In other words, how well your kidneys are working. Specifically measures how much blood passes through the glomeruli each minute. Glomeruli are tiny filters in the kidneys that filters the waste from the blood. Chloride, Carbon dioxide, Creatinine, Anion Gap are component in the blood that tells you how optimal the blood is functioning. You see, we have inorganic and organic components needed to the function of every organ system. For example, Sodium (Na+), Potassium (K+), Chloride (Cl-) are used by the body system. They for example Na/K help the heart to pump is the chemical in the electrical function of the heart. Also, in the cell this pump help the cell to obtain the nutrients and at the same time the cell getting rid of the waste. So, your anion gap tells you weather your electrolytes are out of balance or if the blood is too acidic or not.
WBC = white blood cells: most of the time indicates that you are fighting infection or inflammation. Normal range is 4,500 to 11,000 WBCs per microliter (4.5 to 11.0 x 109/L).
There are three major classifications of WBCs. The main purpose oof WBCs, are to recognize intruders.
1. Monocytes – They have the longer lifespan than other WBCs. They help to break down bacteria.
2. Lymphocytes – They create antibodies to fight against bacteria, viruses, and other invaders to the body.
3. Granulocytes – They kill and digest bacteria, fungi, and many other things. Neutrophils, 4. Eosinophils and Basophils are a subset of granulocytes. Basophils are mainly responsible for allergens. Eosinophils are responsible for parasitic infections.
RBC = Red blood cells Count: Measures how many red bloods cell count you have in the body. A red blood cell counts higher than 6.1 million RBCs in male and 5.4 million for females, and 5.5 million for children. High RBCs count can be due to multiple etiologies. They are dehydration, heart disease, Polycythemia vera, Bone marrow diseases that causes other etiologies in many other cells that are produced in the bone marrow. Low RBC indicates B12, Folate and B6 deficiency. Also could mean that you are bleeding internally.
HCT= Hematocrit is the percentage by volume of red blood cells, white blood cells, and platelets suspended in plasma.
MCV = Mean corpuscular volume = measures the average size and volume of red blood cell.
MCHC = Mean corpuscular hemoglobin concentration is a measurement of hemoglobin in a single red blood cell related to the volume of the cell.
RDW = Red Cell Distribution Width = test the different in volume and size of your RBC.
Platelets = (Thrombocytes), they stop bleeding by clumping and forming plugs.
Neutrophils = A type of white blood cell (Leukocytes) that are your first immune response. Thank you.
