Brief Answer: low iron stores Detailed Answer: hi, your gamma gt, or most commonly known as GGT is usually ordered to evaluate your liver. it is usually elevated in chronic liver disease. Therefore the fact that it is low is good! Basically you can disregard the fact that the GGT level is "flagged" (labs flag values if they are out of their normal range, but having a low value is of no clinical significance). On the other hand the Ferritin is a marker of your iron stores in your body. A ferritin level of 7 is pretty low, and the most common cause of this in a young woman like yourself is the fact that you probably lose blood monthly with your menstrual periods and do you probably do not replenish your body losses through your diet. You should eat foods that contain iron on a regular basis (at least once or twice weekly) such as red meats, and i would suggest you taking iron pills (these are sold over the counter). If your ferritin, and iron stores do not improve despite adequate replacement, or if by any chance you do not menstruate anymore, you should seek medical attention asap. regardless you should follow up with your primary doctor.
