Article: You can go to any drugstore and buy a blood sugar testing kit. Most kits contain lancets (testing needles), a lancing device, testing strips, and a meter to read the results. Many insurance companies will pay for your meter and test strips if you obtain a prescription from your doctor. Familiarize yourself with all the functions of your blood glucose meter, how much blood is required for testing, where you insert your test strip, and where the readout will be. Look at the pictures and read the instructions thoroughly, and if you have any questions or concerns then contact your doctor before trying to use the machine. Most glucometers include a way to test to make sure they are reading correctly. This could be in the form of a premade test strip or a liquid you place on a test strip. These are inserted into the machine and the reading should be within acceptable limits, which the instruction manual will provide.
Question: What is a summary of what this article is about?
Obtain a glucometer and test strips. Read the materials and directions that come with your meter. Test the glucometer before using it.

Problem: Article: Even if you have a normal or healthy bone density score, you may wish to discuss ways to protect and promote bone health through diet, exercise, and calcium supplements or multi-vitamins.  Men and women ages 18 to 50 need an average of 1000mg of calcium and 1000 to 4000 IU of vitamin D each day. Women over 50 and men over 70 should up their calcium intake to 1200mg per day through supplements or a targeted diet. Get calcium from supplements or green leafy vegetables, low-fat dairy products, canned fish with bones, and fortified juices or cereals. Vitamin D is necessary for your body to absorb calcium; your daily needs can be met through sunshine and supplements or fortified foods such as dairy or orange juice. If you have relatives with osteoporosis or who frequently experience bone fractures, or if you are otherwise at risk for bone density loss, it is important to discuss bone health with a professional while you are still healthy. Be sure to reach your recommended daily intake each day and participate in regular exercise to promote bone health. With early steps toward bone density maintenance, many individuals can prevent osteoporosis in old age. If your Z-score is very low or if you only received a peripheral screen that indicated bone density loss, discuss what type of further testing you may need.  If you have very low bone density, your doctor may recommend tests for hyperparathyroidism or another bone scan to confirm osteoporosis. Hyperparathyroidism may result from too much calcium in the blood or a second condition causing a calcium deficit in your whole body. Depending on your dietary habits and other health information, your physician may check for vitamin or mineral deficiencies.
Summary: Ask how to prevent bone density loss. Discuss your bone health before it is necessary. Ask whether further testing may be necessary.

To be an online proofreader, or any proofreader, requires a love of reading. You should enjoy reading several forms of writing and become familiar with a number of writing styles, as well as acquire knowledge in a broad range of subjects. Proofing online text successfully requires a knowledge of correct word usage and punctuation, spelling words correctly and recognizing common word confusions ("then" for "than," etc.), and understanding what the writer intended to say through careful re-reading of the text. Website text you'll proofread will either be sent to you by email, or you'll be given access to a site where the draft text can be downloaded from or edited directly. If you download the text to your computer, you'll need to be familiar with the proofreading and editing tools in your word processing program, such as Microsoft Word's "Track Changes" and "Insert Comments" features. If you proofread the text directly, you'll need to learn whatever online proofing tool you'll be asked to use. Some clients may instead prefer you to print out the text, proofread it manually, then fax it back. In those cases, you'll need to know how to use a printer and fax, as well as the symbols used in proofreading and copyediting by hand. At a minimum, high school courses in English, journalism, and literature will give you a foundation in the language and proofreading skills you'll need to have. You can supplement this knowledge with courses at a college or university, a community college, or online, as well as with online tutorials. Online classes are available from such organizations as eLearners, Universalclass.com, and Mediabistro.com. While classes can give you a foundation in English, the organizations you'll be working with often adopt an established style guide or create their own in-house guide. At a minimum, you should become familiar with the AP Style Guide, used by most newspapers and online news organizations and many websites, and the Yahoo Style Guide, used by many other organizations with a Web presence. Other stylebooks to consider include the Chicago Manual of Style, the New York Times Manual of Style, and the AMA Manual of Style. For an overall refresher on usage, read "The Elements of Style" by William Strunk and E.B. White. In addition to the style manuals listed above, you should have a dictionary and thesaurus and, depending on the clients you plan to work for, specialized dictionaries of medical, scientific, legal, or financial terminology. You should also become familiar with and bookmark reference websites such as Dictionary.com; however, it can sometimes be faster or more effective to look something up in a book than online. Look at books, newspapers, websites, and even the text displayed on TV news programs and commercials with a critical eye. This will teach you to spot errors in spelling, punctuation, and usage of words.
